One issue I did not foresee when converting my mrod to a bullpup and me being left handed is my cheek rests squarely on the less than convenient factory magazine sticking out of the right had side of the gun. My solution, make a left handed magazine for my left handed self.
(http://i1373.photobucket.com/albums/ag380/scharfe1/factorrhmag_zps79109ca3.jpg)[/URL]
1st Step - A couple of hours with calipers and solidworks to duplicate the factory magazine.
2nd Step - Mirror all parts to create a left handed magazine.
3rd Step- Make a plan, write some cnc programs and start machining.
I cut a block of acrylic down to my desired size, first program is the for the "front" of the magazine housing.
(http://i1373.photobucket.com/albums/ag380/scharfe1/magazineblock_zps52e675eb.jpg)[/URL]
I used a block .25" thicker than the magazine housing so I had something to clamp into the vise.
1st step done.
(http://i1373.photobucket.com/albums/ag380/scharfe1/firstmagstep_zps09dc5459.jpg)[/URL]
I then machined another piece of acrylic so I could flip the magazine over and machine the back side. The hole in the center is for a screw to screw from the bottom side into the center of the magazine.
(http://i1373.photobucket.com/albums/ag380/scharfe1/magflipfixture_zpsf8b26c9a.jpg)[/URL]
I was a bit to generous with my offset so I had to shim around the part with some paper.
(http://i1373.photobucket.com/albums/ag380/scharfe1/maginfixture_zpscdc292af.jpg)[/URL]
After running the second program, the "raw" housing is done.
(http://i1373.photobucket.com/albums/ag380/scharfe1/magraw_zps58ea78bb.jpg)[/URL]
Next I wanted to make the housing clear, because...well why not?
I started with 320 grit sand paper then, 600, 800 and finally 1200 all wet sanded. I next used NOVUS compound 3 (from McMaster) and a car buffer to polish the housing. And finished off with some NOVUS compound 1. The stuff is quite nice.
(http://i1373.photobucket.com/albums/ag380/scharfe1/polishedmaghousing_zps76cd84e9.jpg)[/URL]
After cleaning up the print I put all 3 parts together and they fit well together.
(http://i1373.photobucket.com/albums/ag380/scharfe1/asembledlhmag_zps36e26aab.jpg)[/URL]
Unfortunately all things needed to be mirrored for this to work, including the factory left hand torsion spring.
(http://i1373.photobucket.com/albums/ag380/scharfe1/magspringlhwound_zps1de392d1.jpg)[/URL]
I couldn't find anything even close to working for this spring. So I made one my on my lathe.
(http://i1373.photobucket.com/albums/ag380/scharfe1/lhandrhsprings_zps60ee90ca.jpg)[/URL]
And a couple pics with a loaded magazine. I put 10 rounds through it with no issues. Pretty happy with the results. Im going to have to machine the inside piece out of acrylic also though. The 3d printed part is just not up to my standards.

And some pictures of main finished aluminum part that does most the work. And some explanation to what I consider improvements.
(http://i1373.photobucket.com/albums/ag380/scharfe1/alumcenterbackiso_zps4a926c5a.jpg)
(http://i1373.photobucket.com/albums/ag380/scharfe1/alumcenterfrontiso_zps18e4d741.jpg)
Improvements over stock.
1. I added a full circle lip around the top of the inside piece. The hole is just barley big enough to let a perfectly circle pellet skirt through. If the skirt is damaged or misshapen it wont go trough the hole. If it is skirt shape is slightly off the hole will reshape the skirt to its proper shape. (A very small bevel on each hole keeps the aluminum from removing material from the pellet.) This eliminates my need to sort out pellets as much. I have yet to have a stray flyer with this magazine. :D
(http://i1373.photobucket.com/albums/ag380/scharfe1/15pelletcloseup_zps67cf9e02.jpg)
2. The extended the center hole down with a shaft for 2 reasons.(seen below in center of part)
A. The factory hole only makes contact on the center shaft with a thin section of material. The extended shaft takes out a lot of play in the magazine, allowing for more consistence rotation, more consistency could lead to better accuracy.
(http://i1373.photobucket.com/albums/ag380/scharfe1/alumcenterbacktop_zps5772506b.jpg)
B. The factory spring, as it tightens can rub on the stationary shaft of the magazines black housing. The on and off friction can cause inconsistent torque. The extended shaft only allows the spring to rub on the moving shaft, allowing for more consistence rotation, more consistency could lead to better accuracy.
3. I shortened down the inside geometry to only accept .3" and shorter pellets. It is designed around all my favorite pellets, JSB Heavy, JSB RS, H&N Sport Field Target and Crossman ultra magnums. All these fit perfectly where the skirt of the pellet is always held perfectly center by the back full circle. Again allowing for more consistency.
4. I tightened up the hole spacing,refined semi circle geometry and made the stop part smaller so I could get more pellets in a smaller diameter than if I would have used the same method as the factory mag.
And here is the pictures of the 15 round mag. Consists of 6 parts.
External Back Housing
Front Cover
Inside wheel
Spring
.125" shaft insert (allows front cover to move the inside wheel when rotated)
4-40 ss screw
(http://i1373.photobucket.com/albums/ag380/scharfe1/15allparts_zps028f701a.jpg)
And the assembled magazine.

(http://i1373.photobucket.com/albums/ag380/scharfe1/15allback_zpsfb08f4e2.jpg)
I personally really like the clear and aluminum combo on the gun. I suspect the aluminum to eventually run some of the back off my bolt but don't really care. It wont be in there for long anyways.
(http://i1373.photobucket.com/albums/ag380/scharfe1/15roundinmrod_zps1e93b983.jpg)
And one last picture for the other materials and size comparison to a factory 10 round size.

Amazing! Great job!
-
That turned out really good
-
Hmmm... Perhaps this will lead to another vendor?? ;D These mags look great!! Have you ever thought about going in the opposite direction- down to say, a 7 round mag? Like Theoben did? Pics:
7 shot Rapid mag:
(http://www.drapers-airguns.co.uk/images//Gun%20Spares/Theoben/4414.jpg)
Bottom two pics, size difference between the standard and 7 shot mags:
(http://www.theobenusa.com/images/mfr_loading_port.jpg)
I always liked the lower profile of the smaller mag myself.
-
The real question is when are we going to be able to order these? The second question is will it fit a BNM breach for the 22## platform?
-
...will it fit a BNM breach for the 22## platform?
Oooh, THAT's a good question!!! I hadn't thought of that!
-
That is some very nice work.
Steve
-
As a fellow lefty and Prod bullpup owner, I feel your pain! I've just been dealing with the mag sticking into my cheek. Would you consider making a few of these for sale, and maybe for the Prod? I'd buy one for sure!
-
Nice work.
-
That is just......SO COOL!!!! Amazing!!!
-
Droooooool.
I hope you decide to offer these for sale. How about for the big bore folks? 7-round 30 cal and able to swallow boolits .700 long?
chees,
Douglas

Ive never thought about going smaller honestly. I personally don't have a need for one. But on the other hand don't mind a challenge.
-

I don't know honestly. I have never gotten ahold of an BNM breach. But if it will accept a factory mrod magazine, it should accept mine.
-

Yep, I feel your pain is my exact thoughts haha. Im starting to consider making a couple if people really want them. Unfortunately all I have is a 22 cal Mrod, so unless other variations of calibers or guns or aftermarket breaches use the same geometry as my mrod I wont be able to design and test them. I would love an excuse to buy more guns ,but might have to sell a couple mags for that haha.
-
After hearing more interest from people in buying these than I expected I decided to try to write some more efficient programs on the cnc to see if I could feasibly make these fast and cheap enough so that they were NOT the $75 magazine that my initial unrefined programs indicated.
Im definitely enjoying the challenge and I am already on Rev 3 of the magazine. This one is shooting like a dream, I don't think Im going to be able to go back to the factory one. And Ive already decided to scrap my first left handed design based off of the factory mrod and decided to create a 10 round magazine based off of my original 15 round design.
While I was running some programs I had some free time so I decided to clean up some of the aluminum internals, I did a brushed satin and polished finish. They look a bit nicer than my first prototype.
(http://i1373.photobucket.com/albums/ag380/scharfe1/15roundcentertopfinishes_zpsa0f38126.jpg)
(http://i1373.photobucket.com/albums/ag380/scharfe1/15roundcenterisofinishes_zps98e615d4.jpg)
Hopefully I will have some pretty machined prototypes of the 10 rounders soon. Thanks everyone for the comments and interest.
-
Okay, now you've stepped in it! You just created a lot of work for yourself.
-
The real question is when are we going to be able to order these? The second question is will it fit a BNM breach for the 22## platform?
Why sure they will fit the BNM breech, I have one and it uses the 22 cal Mrod mag, so there is no reason for it not to work!
With my Mrod 10 shot mag installed in my BNM Breech I have about 0.48" clearance from the top of the Mag to the bottom of the Scope (Scope is 30mm UTG 6-24x 56mm) using High Mounts and the clearance from the bottom of the mag up to the bottom of the scope is 1.80" Now this is using High Mounts, so low and medium are going to be different.
The 10 shot mag itself is 1.34" in height.
There actually may be more room due to the Mag actually sets slightly off to the side a little...
So, I believe a larger 15 shot or a smaller one will work fine on a BNM breech...
William
-
I like the idea of a smaller mag because:
A) No worries about interference shooting a bullpup, as far as cheek placement
B) Could mount the scope lower to the barrel
C) I like the lines better...
D) If I need more shots than 7, I'll just carry more mags.
I've never personally been in a hunting situation where I needed that many shots accessible at once. I can deal w/a magazine change.
AWESOME JOB AGAIN!!!

The BNM Breach Uses the 22 cal. Mrod Magazine.
So it will work.

Are these for sale?
And do the acrylic/plastic come in different hues/colors?
-
You are an artist! I will chime in with the fantasy that you should manufacture these! But with the reality that you probably have to charge $75 each to make it worth your time how about some fully dimensioned drawings for the various machining stages? I'd love a right hand 15-16 rnd, .25 caliber magazine. I have a buddy with a machine shop.
PM sent.

Im still fine tuning the mags trying to make them as perfect as possible before I consider letting them get into other people hands. I have a couple of attempts so far haha. They all work just don't have that perfect feel yet.
(http://i1373.photobucket.com/albums/ag380/scharfe1/first7maghousingtries_zpsa6a428c6.jpg)
For different colors what do you have in mind the housing or the inside piece. Im always open to suggestions.
thanks
Bob
-
Aluminum or even titanium for the housing, so they can be anodized in crazy colors.

I will also be keeping an eye on this 8) , I have one .25 cal with a BNM breech and this would be a great addition for it and another reason to build a .22 as well. The color would be nice but would be my last factor with 4 PCP's at this point (3 I built and 1 purchased) I really need something other than a hand pump. :D
-
It would be cool if there where a Bright Yellow/Green variant, so it would be easy to spot, if you dropped it, or misplaced it.
-
Nice work. There are a lot of small details which most people do not notice even in such a small devise as a Marauder magazine.

I fixed what Tomg said so it would apply to me. :D

I've made a couple more prototypes over the last few days. I've found that I'm battling a couple issues. First one is that my end mill that I was using for almost all operations what worn out and giving poor tolerance. After putting in a new end mill I'm getting much better results.
Next I think my plexiglass fixture for flipping the part to machine the slot for the barrel (the area that is giving me all the issues) is just a bit to flimsy and isn't giving me good repeatability. Tomorrow I'm going to try to make an aluminum fixture and try again. 8th time is the charm.
I also took into consideration some people suggestions for easy to see colors. I painted (poorly) the inside of a magazine housing with a florescent orange paint. Since its inside don't have to worry about it rubbing off or scratching during use and makes a neat look in my opinion.
(http://i1373.photobucket.com/albums/ag380/scharfe1/orangehousing_zpsb4059c44.jpg)
-
Looks good, I like it, the orange glow is definitely different! I think just about any color would look good that way.
Do they make Plexiglass in different shades? Translucent!
You are definitely doing a good job in customizing thats for sure.
William
-
As far as coloring, you could leave the surface rough, and get with a hydrodipper, and just have them dipped different hunter-safe ( ;D ;D ) colors, or camouflage colors...
I could send you a Rapid 7 shot mag, if it would help you with designing a smaller mag for the mrods/BNM breeches. Keep in mind though, that the Rapid's mag doesn't fit in the Mrod, though it would be a good 3d model to work from. Just an idea.
-
you let me know when you got the 25 cal mags ready for sale,i want one,maybe a 22 cal as well if the price is right,,,thanks, like what your doing.. ;D

You can get it almost any color I believe. I particularly like the smoked acrylic myself. Looks like tinted windows almost.

Thanks for the suggestion hydro dipping is really neet but not sure on the cost side tho. Also thanks for the magazine offer, but I need to get ahold of the breeches for testing tho. I really like my design I have and can scale it accordingly to account for different calibers, breeches and number of rounds. Unfortunately all I have is my .22cal mrod for now.
-
Well after multiple attempts and getting mixed results on the magazine I finally pinpointed my issues, 1 a worn end mill, and 2 sloppy fixturing when flipping the part. To try to get the best the absolute best results I could, I did the fallowing.
1. New end mill
2. Changed from a piece of acrylic to a squared off face milled piece of aluminum
(http://i1373.photobucket.com/albums/ag380/scharfe1/squaredblock_zps25d0d7cc.jpg)
3. Used a new zeroing method that aloud me to machine down to the vise level without removing the z stop.
4. Used a zero offset around the part and fixture.
5. Scrubbed down the vice and parallels (twice)
(http://i1373.photobucket.com/albums/ag380/scharfe1/finishedfixtureand1stpart_zps96b47741.jpg)
And Im proud to say I have one perfect housing. There is absolute no wiggle once it is snapped in. I am finally satisfied with with the fit met. Just need to make a small change to the cover piece and how should hopefully have something that I can call finished.
-
That's awesome!!! If I had any different breech's to send you, I would!! This is great what you're able to do!

Well I don't have a Mrod but I definitely use Mrod magazines in my .25 ca that has a BNM breech and Green Mountain Barrel. I would love to have 12-15 shots per mag.
-
WoW!!! I want one,very well made.

I have been giggling about your proposed pricing; if you want an off-the-rack mag for a Daystate or FX, you're into ~$100. I'd be more than willing to pay that much for a custom for long .308 boolits. The work is fantastic...I patiently await the opportunity to buy some of these jewels you produce.
cheers,
Douglas
something to swallow these: http://www.gatewaytoairguns.org/GTA/index.php?topic=72024.0 (http://www.gatewaytoairguns.org/GTA/index.php?topic=72024.0)
Not sure I'd want any, or at least much increase in capacity; I anticipate a tune for one 7 or 8-round clip/fill with a 250 Bar tank.

Wow thats one big chunk of lead. What beast of an airgun would be lobbing out these cannon shells?

Just a modified Marauder....LOL

I did some tests today to try to speed up the polishing procedure. It currently takes me 30-60 minutes a pieces to remove the machining marks and polish the acrylic back clear.
For a new method I tried to flame polish the acrylic. My results were mixed but I don't think it will work for me. It can easily misshapen the part and also caused some yellowing. I think I can get a little better results with practice but the parts take to much to get them to this place to risk destroying them with a little to much heat.
Results are below , Left to Right, Machine Finish, Flame Polish, Sanding and Polish
(http://i1373.photobucket.com/albums/ag380/scharfe1/3magfinishesfront_zps595dc2ac.jpg)
(http://i1373.photobucket.com/albums/ag380/scharfe1/3magfinishestop_zps74920900.jpg)
Sanding and Polish is the clear winner unfortunately.
-
I agree with you, the most laboring seems to always look the best! Cant wait to get one from you for my BNM Breech. You let me/us know when you have them ready, I want one or two!
Thank you
William

If you offer these up for sale, why not offer sand/polish as an option with extra cost to reflect the work involved? I for one do not care for flash- I care if it works, and works well. Your mags seem to look like they do, and that's all that should really matter. The colors, polish, camo dip (if you can find a dipper who will work with you on price), all that should be a secondary concern.

I think you hit my exact thoughts. I think I might loose my sanity if I had to polish every single one of these haha. The pellets can be seen easily through the front of the already clear face. I prefer the polished look, but definitely not necessary.
-
I seem to "remember" a acetone/xylene dip process, doing the same as the flame polish, but is more uniform.

+ 1, I could polish my own IF I felt a need, I really doubt I would.
Bob if you don't make .25 cal you will be forcing me :-[ to buy another .22 cal with a Mrod or BNM breech, so Please make the .25 cal too 8)

If you had a couple of kids, you could have them round up their friends for a weekend pizza/polish party. Then again, I have a few kids myself. And I'm not so sure I'd trust them around power tools.

Alright, I had a long but successful day. I am happy to announce that I have finalized all cnc programs(all 18 of them) that are necessary for making a 10 or 15 round (left handed for now) magazine. I believe I have the proper equations to scale this design for different calibers, #rounds and even different breeches if they function closely.
Here is the all new 10 rounder (lh), based off of my 15 round design.

And the 3 machined parts

And some size comparisons to the 15 round mag.

And a size comparison to the factory 10 round mag. The ten rounder ended up being slightly bigger than the factory mag due to the integrated "go-no-go" ring.

Below comments are 100% thoughts right now, nothing is finalized.
Ive done ALOT of thinking about price if I were to offer this for sale. After ALOT of thought and calculations I ended up at
$50/10 rounder shipped (machine finish)
$60/15 rounder shipped (machine finish)
+$10 each if you wanted it sanded and polished clear - I have happy to make a how to for you to do it yourself
I would pay shipping and only paypal would be accepted and I would absorb the paypal fee. Im trying to be as fair a possible just trying to not loose my shirt on the deal. (If) any and all profit would go to the continuing development of cool things in this hobby.
A couple of precautions and notes.
1)The quality that would be received is shown in above pictures (i will clean the parts better tho)
2)The inside part is raw aluminum, it could rub some of the blueing off of your bolt over time.
3) I will be in no way responsible for how you use this product.
4)I want nothing but positive things to come from this, for any reason you were to have a problem, comment, or suggestion, I will work with you.
My final thought is how many people would want these. I have created programs for the left handed magazines because that it what I wanted. I really have no need for right handed magazines, but I am willing to design and put the effort into making them if there is enough interest in them.
At the top of the page is a pole for judging the interest in this project.

Yes. This is the way to go! But I'd charge way more to polish if it's taking you an hour each! I'd charge $25 - $30 each!
I also second the thoughts of daniel kyle above! I have a .25 Marauder and NEED a 12-16 rnd magazine! Hopefully I'll soon own Marauder Pistol and we'll need to "talk" further! ;)

I forsee a .25 synrod in my future. So I didn't vote. But if you had a .25 option, I'd most likely go with that. Didn't want to skew your poll.
I also agree that the polished version should be at the bare minimum $20 extra.

Don't suppose anyone with a scoped benjamin marauder would want to check if this 15 round magazine would fit on their gun. I have a bullpup so no issues for me haha

Replace your 0.83 with 0.86", and that is what I have on the BNM Breech in clearance with High Mounts, that is to the bottom center of the 30mm scope. So it will fit a BNM breech with High mounts with no problem. Not sure about if it will fit using medium scope mounts.
I dont have a mrod but if the BNM was copied exactly off the Mrod breech it may work.

With the amount of work involved, plus the possible ability of getting a smaller mag due to the programming, $50 is a deal!! Here's why, and keep in mind these are prices from a reputable airgun dealer:
BSA 10 shot: $82.50
Daystate Harrier X & Mk3: $119.95
FX Cyclone (No moving parts!): $30
FX 12 shot: $89.95
I feel that $50 for a U.S. made mag, that can be modular, with this level of quality is absolutely worth it. Even at $60 for the 15 shot is still well below all the other mags I listed above, that have moving parts!

I ended up making a right handed 15 round magazine. Was much easier just having to mirror my lh design.

One of the reasons I did this is because two of the parts would be needed for this. I call it the "behemoth" and it will be my 30 round mrod magazine. Don't have the time to make it yet, but I messed around with some renders for it.

A 48 shot Behemoth would be pretty cool for my local Field Target Match.

I think that it would help to get the pellets closer together which would give less movement between shots. I feel it would be less damage to the pellets with less movement. I get better groups with single shot feeder I made than with magazine. Prefer the magazine for convenience. I load up my 12 magazines and shoot 3 40 shot strings.

Their is actually a semi circular geometry in the bottom side of the aluminum piece. And also an inside retaining ring in the main housing piece. All the pellets are held very securely and consistent. With a high quality pellet you can't even hear the pellets rattling when u shake the magazine.

What keeps the next pellet from falling into the chamber before you are ready to push the bolt in on the 15? Just curious or crazy one.

I broke out the calipers & measured the distance between the top of the breech to the bottom of my scope. Got 0.78" with Leapers high rings.
-
I am thinking that the measurement needs to be taken from the bottom of the breech slot where the magazine actually sits to the bottom of the Scope, then use the height of the new 15 round clip to decide if it will fit on the Marauder!
Anyone got the actual height of the Marauder breech (22 cal) from the point of where the bottom of the clip sits to the very top of the Breech (top of dovetail mount rail)?
Once you know that and the actual height of the 15 round Magazine then you will know if it is going to fit!
I think that is what we need to know!

I'd do 15 rounds if it fit Prod, why no. 25 extended mags?

scharfe,
Does not have a .25 Mrod and he would need one in order to make sure the Magazine works properly, unless he could maybe get some exact measurements on the dimensions!
Wish I still had my .25 Mrod I would send it to him so he could make some mags for it!

When you turn the cover to load the magazine it winds a torsion spring. The spring puts a little pressure on the pellet that is pinned between a stop that aligns the pellet to the barrel and the geometry that holds each pellet, locking the pellet in place.
Thanks

Got a chance to do a full 150 round test with the first right hang magazine today,(pretty difficult for my left handed self and my bullpup) also probably put over 500 rounds through some left handers. Zero issues so I am pretty happy with it.
I really happy with with the accuracy and my goal of building a "precision" magazine may have been a success. I am no sharp shooter but I do feel that I have had more consistent shots with less stray bullets than I have with a factory mag.
One thing I found amusing is how obvious this magazine makes slightly less than perfect pellets look. Below is a picture of two of my favorites pellets, the crossman primers on the left (favorite for price) and jsb heavies on the right (favorite for accuracy) My picture doens't do the obvious difference justice in the shape of the pellet skirt.

Be a close fit I think, but it looks just from estimating some of the figures you should have room for it to fit with a little extra. (That is using High Scope Rings). I am sure some High rings are actually higher than others.
Not sure exactly about the fit but Bob would be able to figure it better than me!
So, if you have 0.78 clearance for top rail to bottom of scope and the measurement from the bottom of breech mag slot to top of rail is 0.9785 and if the magazine is about 1.88" this would be. (dont forget the mag is offset a little giving you about 0.11" extra room!
0.9785
+0.7800
= 1.7585 This is the approx clearance you would have plus what ever the offset is that would add about 0.11" extra.
+ 0.1100
= 1.8685 total Approx. Clearance you would have. Do not take my figures to be correct, just getting an Idea of what to expect.
I do not know exactly how high the 15 round Magazine is, only Bob would know! It looks like it will work without a problem, I believe there is more clearance than what I have figured. I definitely know it will work on my BNM Breech with High Mounts.
My BNM Breech is the same measurement as the Mrod +/- .001" from the bottom of breech area where mag sits to top of Scope Rail.
Bob,
Am I close or is this wrong, it looks close to me?

William,
I believe we are both trying to skin the same cat but with different methods. The magazine sits flush with the bottom of the breech. Our measurements should only vary by cossman's tolerances from the bottom of the breach to the top of the scope rail and measuring error. For me the distance from the bottom of the breech to the magazine are as fallows.
(http://i1373.photobucket.com/albums/ag380/scharfe1/extramrodmagdim_zps42afd6ee.jpg)
If your space from the bottom of the breech or top of scope rail is larger than the spaces show, it should fit. If it is not but more than the distance to the top center of the bottom breech or top of scope rail it will depend on the diameter of your scope tube above the magazine if it will fit.
-
Thanks Bob,
It will fit and have a little room left, just it will have to be used with High Scope Mounts. You have done a great job on the customization thats for sure.
As soon as you're ready I will be getting one! Let me know when you get setup in the Hobbyist Classified Gate. I cannot wait to give one of these a try!
Thank you,
William

Bob is there anyway to add something to your magazines to prevent double loading ?
This is one issue with the Marauder Magazines that would / should be looked into. Looking at the way the magazines are made I cannot see anyway to do it but possibly you can find a way.
Norm
-
I don't think the double pellet loading is a magazine issue. It's a rifle issue. My Rainstorm-1 doesn't allow double loading. How do you make a magazine that knows if you've already fired the previous pellet?
-

That's part of the reason why the Daystate mags are so fraking expensive. It's a set up in both rifle and mag that uses air, I think, to drive a pin that prevents double feeding. Too complicated, and more importantly, expensive IMO. Something like this would need a whole new breech I would think.

Norm,
I did a quick sketch up of a concept for a magazine that would prevent double loading. But like a couple of other people said it would be very complicated and crazy expensive to make. Probably wouldn't end up being very reliable either haha. I also think like YEMX212 said a new breech that would allow some sort of communication between the mag and breech would be necessary to get it to work properly.
-
I still have a couple "tester" mags or anyone interested, I would like to get couple more out in the field testing if possible. If anyone is hesitant in getting one because of the need for self fitting the magazine I figured would show what would be necessary. Also "tester" may be the wrong word haha. I come from a production company that has very strict quality standards, most of which I have developed and enforce, so I may be a bit to strict with my own designs haha.
All modifications should require removing very small amounts of material. I would recommend sand paper or a small fine file. And go SLOW you can always remove more, but cant add it back. Its actually really simple.
(http://i1373.photobucket.com/albums/ag380/scharfe1/mrodmagfacetomodify_zps2348a86f.jpg)
Red Face
This face will most likely be one one that will need to be modified if it is to hard to slide into the breech. Slowly remove with sand paper on a flat surface or fine file. Go slow be patient.
Blue Faces (top and bottom faces)
Is the starting alignment for the barrel. This should not need to be modified as I believe Crossman would hold a tighter tolerance on this.
Green Faces (top and bottom)
Are the locking nubs, they snap and lock the magazine over the barrel, if it is to hard to to snap in or out the nubs can be lightly sanded on
If done properly the magazine will lock into the breech with no movement once it has snapped in place.
-
Scharfe,
Thanks for the how too, My factory magazine needed this also, so I used fine sandpaper and sanded a little at a time so it would slide in and snap into place without a lot of effort. Like you mentioned do a little at a time, it doesn't take much! Also if the area that you need to sand on is flat, lay the sandpaper on a good flat surface and rub the magazine on it.
Thank you, can't wait until mine arrives, I will give a review on it here when I get it.
Thanks
William

It is a great idea Norm! ;D But PB magazines don't even have this feature, so I wouldn't expect an airgun's magazine to have it. Unless you have a lot of money for R&D, and are Daystate, and no. Just- no. ;D ;D

Isn't most of the double loading the shooters fault. I know I have loaded before and got sidetracked and instead of checking to see later I have loaded another. Especially during starling season around here. So far only messed up I set of baffles.
Bob
-
Of course it is the shooter's fault for double loading! If any product is used as it should be there are usually no problems but like anything else at times we all make mistakes. It is always nice if a way is found to prevent human error from happening when using a product, which would be a plus. In the case of the MRod magazines there is very little chance that it will ever happen. I am sure that over time there has been more difficult things that have been solved and who knows maybe one day we will be able to say "why didn't I think of that"

Sorry couldn't help myself.

The only magazines that are not expensive and don't allow double loading are the ones that don't rotate themselves, instead the action of the air gun does it an example will be the Hatsan PCPs or the old style Evanix Rainstorm. Both of these air guns actuate a lever that rotates the magazine but once that the hammer is cocked that lever locks into place and can't be moved again, you can still open the side lever or bolt but it won't actuate the lever.
Far more expeensives magazines like the ones from the Daystate Wolverine line of air rifles use another magazine that actually doesn't rotate itself what rotates it is a small pin that is released when you operate the bolt, but it can just be released once since the force that pushes that pin is actually air from each shot. Far more complicated system that will be very expensive, however if you really want a magazine that doesn't double loads itself you could look at the Hatsan AT44 breech but you will need to re-design the magazines. My advise would be to leave the magazines like they are now and add a small device like the shot count device you have that turns on a small LED when there is a pellet inside the barrel, still you would be able to double load the gun but it would be less common.

Got my 15 round .22 Mrod Magazine from scharfe today, so here is my thoughts and a little review as well as what is needed to get it running smooth and fitting into the breech.
First of all, My .22 is a Disco with a BNM Multi-shot breech which uses the Mrod Magazines.
When I got it the spring needed tightened up, so I pulled it apart and wound the spring a little tighter so it would feed, (may have gotten bumped off while shipping) I tried to stick it into the breech and it was too tight, so I got out the 400 grit sandpaper and sanded the bottom until it would slide into the breech with very little resistance. Well it would not go due to it hitting the scope, so I sanded a little extra off the bottom, a little at a time until it would snap into place and feed pellets really well.
Even after fitting, it still just touches the scope, (maybe .001" clearance).
Pictures below so you can see the differences, the only thing I had to modify was the very bottom of the magazine where it sits down in on top of the breech. NOT the GROOVE that Snaps onto the barrel end.
Make sure you only sand the bottom, that is most likely the only place it will need modified, look at the pics and notice the red dotted line is where I sanded, (the bottom is the flat part you cannot see).
Now, if you do not have a scope setup using High Scope Mounts then the 15 round clip will probably not work! It will work just fine on a Bull Pup.
My Thoughts,
The good- everything this is a very well made Mag that with a little fitting works like a charm, I give it an A++ ;D
The Bad- Nothing, except you will need High Scope mounts.
As good as this works I can bet you the 10 round clip works way better than the factory one!
Please dont mind the plastic dust on my Disco from sanding and fitting the magazine!
Thank you, scharfe you did a great job on these.

William thanks for the feedback, for your specific situation with only .001" of clearance needed you could shave the circular part of the magazine that is touching the scope tube. The wall is .05" thick at its thinnest point (just top .06" of housing, rest is .1" thick). If you were comfortable with modifying it you could shave it the fit the contour of your scope, giving it that super custom fitted look.
thanks again

I did think of doing that, but after taking a little more off the bottom it snapped into place and worked good, if it does act up later I may do that. I seen there was plenty of room for contouring it around the scope a little, I even marked it and was just about to sand the edge!
The 15 shot mag will make a great hunting mag for sure. Fill it up and you should have a good hunt without having to reload it. The original is smaller so it makes a nice backup to carry in your pocket in case you need it.
I will give it a workout this coming weekend and see how she goes from there, I will let everyone know how it went and if I had to modify it anymore. I think it will be fine as it is feeding very good.
William
-
wow, that is really close clearance w/the scope... Hmmm... unless a shooter wants high rings, maybe market the 15 rnd magazines for bullpup builds? ;D
-
I just received my 10 rd mag today- I haven't mounted the scope on my rifle yet... but it fits the breech perfect! I may have to actually fiddle w/the barrel fitment, as I feel like the mag fits a little loose. There's a definite "click" into place though. I'll fiddle with it tomorrow to see if it's the barrel alignment. So far so good though! The mag feels amazing, very tight tolerances! When scharfe said you could barely hear the pellets rattling around in the mag- boy, he wasn't kidding! I look forward to putting some lead down range!! This mag doesn't feel flimsy at all.
As far as needing some light sanding on the bottom for fitment- not needed for my breech. It slid in, no problem. It does fit tighter than a factory mag, but that's a plus for me. More tomorrow!!

hmmmm. I thought I left more than enough material on it to account for some pretty generous tolerances on the breech. Does your mrod have a stock breech and barrel?
All magazines that I test with my mrod are very tight to fit in, usually takes two hands to get it to snap back out. My personal mags snap in a little tighter than my factory mags but there is zero movement when it is snapped in.
-
If it snaps around the barrel it should be lined up, even if it is loose on the sides or bottom. The grove is what lines it up to the barrel chamber, so I don't see a problem with it being loose as long as it snaps in place. I also don't think it needs to snap in very hard either because once it is in place and the bolt is pushed forward it is not going anywhere.
I actually like mine a little loose, but not rattling loose, makes it easier to insert and remove. I had to sand all my factory Mags due to they were too hard to get in and out, I thought I was going to have to use channel locks to grab and pull them out, even on my .25 cal Mrod.
Just my thoughts and I have never had a problem with them being easy to insert or remove (as long as they snap into place).
These are really good mags for sure ;D

I have a stock .22 breech, Gen1. That shouldn't matter? I assume the mag-well tolerance is the same for both Gen's. I do have a TJ barrel from Jim Gaska. But the barrel fits tight in the breech. Again, I may not have the barrel seated properly- I kind of slapped the rifle together to see what it was like assembled. It was in parts for way too long, and I needed to see it all together.
-
YEMX,
As long as the barrel is sticking through the Breech the Mag will clip on it, just be sure you're fully seated in the receiver with the barrel so that the Transfer port holes are lined up. If the Mag is snapping onto the barrel then the Mag will be lined up correctly with the bolt and chamber, even if it rocks left and right it will still be in line with everything (thats the way it is designed)!
Good luck and enjoy
William
-
Yemx, as for the gen 1 or gen 2 breech I don't believe there should be any difference, they do use the same factory mag as far as I know. The fact that yours is a little loose is pretty surprising. The dimension that mainly affects the tightness is the distance from the bottom of the barrel to the bottom of the mag slot in the breech. The fact that yours is a little loose means that crossman is much more generous with tolerances than I thought, but I guess as long as the the barrel and bolt are aligned should be fine from crossman's standpoint.
As William said when the mag snaps onto the barrel it is centered. I was hoping for perfection and zero movement when its custom fitted to each persons breech. Looks like one mag fits all perfectly won't be an option, all will probably require hand finishing. Ill probably have to add a little more material to the bottom of the mag to account a little more. After you get a chance to test shoot it, if there are any issues let me know.

Also, William and Yemx the whole aim of this mag was to hopefully, by adding tight tolerances and a no-go-no gauge that it would lead the better consistency that would lead to improved accuracy over the factory magazine. If you notice any accuracy changes or reduced fliers let me know. My available shooting range is a bit short so as I think I'm getting better results I'm also byist so would enjoy hearing other peoples opinion.
thanks

Got a chance to go out today and shoot a few full Mags of pellets through the 15 round magazine. Works perfect no hesitation or sticking, smooth as butter.
This is a big difference in quality when you compare it with the factory magazine, the 15 shots sure take longer to shoot thats for sure. This is a great magazine for hunting, you will only need one mag for a hunting session which means less reloading and fiddling around.
Remember if you get one of these 15 round magazines for your Marauder or BNM breached gun you must use High Scope mounts and you will need to do a little sanding to make it fit into your breach, further back in this post is instructions for the fitting if needed. Some Airguns may not need any modification to the mag to make it fit!
I only had to sand a little off the bottom of the breech for it to fit to my desired tightness.
Thank you Scharfe for making such a great product ;D

Bob,
Looks good, I'm guessing but as smooth as it is, it almost looks like a powder coating!
I am thinking though that if it is, what I think it is, that new item you purchased must be a really good one, not going to mention what it is, that way if Im wrong nobody will ever know lol
Updated-- Ok Now I see what you did!
Looking good, I like it ;D

Trying to get some data collection for pellet sizes going. If anyone has some data they would like to share, the new post can be found here.

Alright, finalized my mrod magazine design, and took the plunge and had 25 of the aluminum parts hard anodized in black, figured out how to get an almost perfectly clear machine finish.
They will be for sale on the Hobbiest Classified Gate

A couple final modifications.
1. Added a slot to allow easier opening and rotating of the top plastic piece

2. Got rid of the press fit insert for rotating the center piece, and machined the feature into the aluminum piece.

And a couple more pictures, Im very happy with the final product.

I see you've been busy, excellent job. I like the black center and adding that notch to spin the top piece was an excellent Idea.
Took me a few minutes while on my last post to figure out you anodized the center piece, I figured it out when I seen that you named one of the pics "anodized _zpsfaky8c3p.jpg", you really have done a nice job on these and I will be looking forward to seeing more of your improvement projects in the future.
Excellent ;D

Good catch on the anodize haha. Hopefully, funds permitting, there will more fun stuff in the future.

I had decided to find myself a Gen 2 Refurbished Marauder in .25 last week, due to all the glowing posts I've read, and the many successful mods & parts being done. This outstanding production just further enforces the Marauder as a best bargain for a natural tinkerer willing to dig in & customize. So, I'll be watching for the .25 cal version of your magazines!

Hello please please sell me one of these in .22 I need it for my feild and target marauder I’ve looked every where help me obi one kenobi your my only hope!!!

Haha, I still do have some of these, they are built to order $60/pc. Please check that if you have a scope it will clear the larger magazine, page 5 of this post shows about how tall your scope rings will have to be. I used to have detailed instructions on how to check if it would fit but it looks like they have expired. Trying to find them back now.

Hey, Bob, just saw this tread of yours- nice work, man! I did not read thru all 6 pages, so forgive me if I ask and it’s been answered already. 25 caliber magazines for my synod, do you make these, also? What about for the 22 caliber P-rod?
Let me know, and thank you

I only own a .22 cal marauder, so that’s the only magazine that I’ve been able to develop and test.

That is a sharp looking magazine, Great job. 8)
Have a question for you, if you don't mind,
I have a repeater action that takes M-rod magazines, 22 cal, can't mention the name, (arrow guy)....
will these magazines fit that action?
Can you provide these dimensions, for the 10/15 rd magazines.
maximum thickness, total overall height, I am curious to see if your mag will fit this action.
Measurements of this action:
I have 1.600" from the bottom of the magazine slot to the bottom of the scope, using the tall rings, (unknown brand name),
.320" clearance from the top of the mag to bottom of the scope (1.000" diameter scope.)
Magazine thickness (opening for mag) is .600" wide, bottom of the bbl to bottom of the slot is .200",
from the end of the bbl to side of the slot is .530".
I hope all this makes sense.
Thank you,
Don

Please see the dimensions in the photo below. I believe this magazine might be too tall for you current scope rings.
The magazine is .588" thick.
The bottom of the slot for the barrel to the bottom of the action is about .183"
This magazine was designed to be interchangeable with the mrod magazine, but I have only tested it on a mrod, so I can't say it will fit anything other than that. You are welcome to try as long as you are ok with paying return shipping if it doesn't work I would refund you.

I can't lie, it was so unique and pretty (looked unused) that I set it aside and kept using the OEM ones, so I can't offer a durability report.

Mine is holding just great after a few years.... works the same as the day I got it from you ( :

Your magazines should be the benchmark of all Mrod magazines! That thing was so tight, and had little to no play! It fed pellets beautifully and I never had an issue with it! Everything from loading the mag, to snapping it into the breech was crisp and satisfying. I only put around 100+ pellets through it. I hated to part with it, but at the time, I didn't foresee any projects in .22 caliber that could take Mrod mags...
