I've been working with the Disco Double tube design some more to simplify it from the Disco Fever .25, and make it easier to install. I switched to 7/8" O.D. tube (same dia as the Disco main tube) made out of 4130 chrome moly tubing. The new tube almost exactly doubles the standard volume of the Disco. Twice as many shots, or more shots at higher power or bigger caliber.
The mechanical installation is strictly hand tools. The tubes are connected together at the front end with all new custom parts. The barrel band is special. The pressure gauge gets left where it is, as is. The only hitch is that the stock has to be routed out forward of the gauge to accept the new tube. Other than that, it is a bolt-in job.
I think this could work pretty well for a hunting carbine, too. The main tube and barrel could be shortened, and a matching shorter second tube could be added, and you'd still end up with more air than original.
I'd love to hear some thoughts or suggestions about this project.
Thanks,
Lloyd-ss

I think it is an awsome design Lloyd. Hunters dream sort of speak.
Questions:
1. Does the guage adaptor and valve come with it?
2. Can a .22 barrel be used with this configueration?
3. What would you say the overall weight of gun is after complete?
4. Would there be any restrictions on using an M-Rod trigger group and with this design as long as stock has cut out for trigger group?
5. Can I assume that aftermarket breech' s can be used?
Enough for now..:)
Thanks

Gene,
I am glad you like it, and I appreciate the comments!
Here are the answers:
1. Does the guage adaptor and valve come with it?
-------The gauge and adapter that are on the Disco that is being modified will be reused. In fact, the only part of the Disco that isn't reused is the fill nipple and it's adapter. Everything needed will be included in the kit.
2. Can a .22 barrel be used with this configuration?
--------- Yes, this will work with any Disco in any caliber, with stock or custom breeches, and with moderators or brakes, too. It will have plenty of air for a high powered .25.
3. What would you say the overall weight of gun is after complete?
----------- A stock Disco weighs about 5 lbs 2 oz. This kit adds about one pound.
4. Would there be any restrictions on using an M-Rod trigger group and with this design as long as stock has cut out for trigger group?
--------- Yes, the M-rod trigger will work fine.
5. Can I assume that aftermarket breech' s can be used?
--------- Yes, it sure would. In fact I have a special breech I will be installing very shortly and trying out.

So it will remain at 2000psi just double the volume? Will you have the capability to anodize these or powder coat them to match the stock tube? What do you predict the cost to be. I'm very interested!!!!
Thanks Lloyd for your forward thinking and design work in airguns.
Happy Shooting!!!!

Thanks very much Dave!
Yes, technically, it will remain a 2,000 psi gun, but I will test all of the kits at 3,000 psi. My calcs (and the calcs of others) show the 3 screws that secure the valve assy to be the weak link. That can be fixed.
I need to line a finisher up. Where I live, I think powder coat will be the least expensive option, but I am checking anodize, too.
I am not sure about the price yet (still talking to CNC guys), but probably between $100 and $200, which would include all the parts shown in the 3rd picture.
Possibly also have a "service grade" version that is unfinished and less expensive? I am open to ideas. The wide barrel band could have custom CNC engraving (including line drawings) on it if anyone was interested.
Lloyd
-
thats awesome and kits for this type of stuff is going to be a huge bonus to the airgun hobby..
lloyd have you thought of using that gun kote stuff as finish? it would be something that you could do in ur shop/kitchen if you can clear it with the lil lady.. other then the cost of the gun kote which im sure one can could finish a few airtubes and parts, you wouldnt have to pay anyone else for doing finishes.. heck i think these will be a big enough hit you could buy a cheap used oven to bake the gun kote in..
-
Mike,
I went back and looked at the GunKote thread. It does look pretty good. The tube is steel, the fill nipple is stainless steel, the end plugs and barrel band are aluminum, plus, there is a black Delrin protective cover. I wonder how the GunKote will work on such varied materials (minus the Delrin), but no matter what, I ought to try it. I wonder if there would be interest in a budget unfinished version?
Lloyd
-
It couldn't hurt to have kits that are unfinished, I just thought the gun kote was a idea worth posting. Cuts out the middle man for doing finishes and puts more money in ur pocket..
-
Mike,
Yup, right you are. I see that Midway has it in aerosol. I needed a reason to get a Midway order together anyway. ;D
Thanks,
Lloyd
-
Ur welcome, gun kote is kind of pricey but one tube should handle more then a hand full of orders
-
I'm sure a few unfinished kits would sell,,, for folks who want to send the off to Shadow, for a camo finish, or try to finish themselves. Great work there!
-
I've used Gun Kote on various steels and aluminums and the color is consistant. I'm color blind and shade variations show up big time for me.
I would think that there would be interest in a kit that is in the "white" for people who have or want to camo there hunting gun.
As for a shorter version I would wait and see if there is enough interest. At just over 5lbs it is still a light rifle for hunting.

You always can use that word "Options"

I have been following this thread and I must say - Lloyd SS - Sir, you have it going on.
If I could change one thing, it would be to have your brain. ;D
Someone else posted you just had a Birthday, Happy belated Birthday Sir.

Thanks very much! And yes, it is birthday time for me, even though it's long past the time when I wanted to start skipping them.
I do appreciate all the feedback about the double tubes for the Disco.
Lloyd
-
i want it. would make the disco much better for winter hunting. plus the added weight would be great IMO. deffinatly will keep an eye on this. how hard is it to install?
-

Mechanically, its very easy to instal with only a few hand tools. The stock does need to be routed out to accept the extra tube, and that will be the hardest part of the installation.
Be careful what you wish for, LOL. ;)

This looks AWESOME!!
One quick concern/test is that when we played paintball with CO2 guns is that every now and again a O-ring would freeze and fray and break and release all the CO2, What is the possibility of CO2 degrading any of the new parts in this system
Other than that this is sort of epic haha

Nathan, Golly, I really don't know. I have no experience with bulk fill CO2, but all of the new o-rings in this double tube application are static, so I would not expect any problems. However, the passage that ties the two tubes together is very small in diameter so there could be a venturi effect if it was filled at a fast rate and that could create localized cold spots during filling...I am not sure.
What do you think?
-
lloyd, I don't even own a Disco, but this mod is fascinating. To think of the possibilities for shot count and energy in .25...just excellent. Will you offer a a complete .25 version for sale (with a full shroud, maybe)?
looking good, man,

Darryl, if Lloyd does not offer a complete gun I would be glad to help you out...:)

Darryl,
Thanks, man, but for the time being, I am just going to stick with the producing the kit. I don't want to over-commit and then not be able to keep my promises. Sounds like there are options, though. ;D
Lloyd
-
rgrt ;)
-
very cool idea, this is something i would definitely be interested in once you get it in production. My only concern would be altering my stock, would there be a template or directions or possibly the ability to send the stock in to have it done. Id much rather pay someone to do it then try it myself, im just not good at stuff like this.
-
Scotty,
I am working on an arrangement for getting stocks altered. For someone who has the correct tools, its a very very straight forward and low risk alteration. If you look at the front of the Disco and picture a second air tube of identical diameter Siamesed tight to the bottom of the original, that's where the wood will have to be removed.
Lloyd
-
Get the stock secured in a rock solid clamp and the correct router bit. Should only take one or 2 passes to get the airtube channel cut deeper...
-
Lloyd.... you've done an excellent job not only in testing this product but in figuring out how to bring it to market as a kit.... My hat's off to you....

Bob,
Well, Thank you very, very, much! That means quite a lot to me, and I will live up to the expectations.
I (and all of us here) are so glad to have you back with us. Many times when you were in the hospital I'd read a thread and think to myself, "Bob would be the person to field that one. He's got the answer, and the data to back it up!"
Best regards, and welcome back,

I just scored a QB78 target stock and I'll be routing it out and installing the Disco Double action in it tonight, with pics. Here is a Disco stock with the Disco Double action, and the new (to me) QB78 stock.

Does the fill port move to the bottom tube? How much barrel is left sticking out for mounting appliances?
Regards, Tom
-

Regards, Tom
Yes, the fill port moves to the front end of the new lower tank. Both tanks will have matching end caps. The gauge stays where it is on the main upper tank. The tanks both stick out the front the same distance as original.
I might offer an option of shortening the tubes for carbine applications. The new tube would be shorter and then you'd send the original tube from the gun to me to be shortened to match. The double barrel band (with option of a third top hole to capture the barrel or shroud) I am making will have a short section of Picatinny (Weaver) rail on the bottom for a bipod or sling.
Lloyd

great idea Lloyd;makes me want a pcp,would this also work on the marauder as well?
-
I would take one in a min but have zero wood working skills. That would exclude me from purchasing one. Real bummer.
-
grumpy you could always look up a cabniet maker local to you or any local wood working shop. take them the stock and the airtube and see if they would run a router down the stock.. should only take a couple of minutes...
id think even a dremel with the router setup on it could handle the job
-

Hadn't give much thought to the Mrod yet, its air tube is pretty big from the factory. But once the disco one is underway I will take a serious look.

Come on Grumpy, absolutely ZERO woodworking skills??? Can ya whittle a tooth pick? Seriously, what Mike says is right.
Also, I am getting a website set up that will have some do-it-yourself videos of the install and stock modification. Plus there are some folks on this forum that I bet will be happy to offer the service of doing the stock mods for people.
Lloyd
-
i even thought of a wood file, pull the plastic handle off and take a metal handle onto the flat side then use the curved side and run it up and down the stock to file the airtube cut down to fit.. it would take longer but could be done that way.. even a decent set of chisles and working slow then doing a follow up with a file and sand paper
the wood on the disco stocks is very soft in terms of wood..
-
Zero man. If it involves wood skills, count me out. I cant make a straight cut on wood to save my life.

Just use a 13XX or 22XX pistol action and a Crosman plastic carbine stock. The lower tube would help make the pressure gauge look better. A forestock could be mounted to the new tube clamp. Regards, Tom
-
I worked on the QB78 stock and routed out the inside to accept the Disco action. At 5/8" wide, the disco trigger is wider than the QB78 so that worked out fine. The slot was about 1/4" too long, but is ok.
I just slipped the Disco Double parts into the freshly routed stock to see how they might look. The stainless tube showing thru the peek-a-boo slots in the stock look pretty cool, I think.
QB78 stock fully routed for a Disco action.
(http://i226.photobucket.com/albums/dd79/loyd500/Disco%20project/Disco-QB78-3.jpg)
This shows how the slot for the tube has to be 7/8" deeper than standard.
Both tubes are 7/8" diameter.

Disco Double tube kit in a QB78 target stock.
The front ends of the tubes would normally be even, not stepped.
The barrel band will be different, too.

Looks nice.... Gauge on the front of the tube?....
Bob

Bob
Bob, Normally the gauge would stay unchanged in its original location on the main tube, thru the hole in the stock. Because this stock had open slots in it, I thought bringing the new tube all the back past all the cutouts would look better. In this case I would probably move the gauge to the side of the lower tube, but out very near the front. I want it visible when filling, but not in the way or vulnerable.

Bob
-

Bob
Yes, you could, but then you'd have to plug the original hole in the main tube. The plug for the lower tube could stick out from the back end of the tube by 5/8" or so and then could have a tapped hole to accept the gage.
-
Ahhhhhhhh.... enter the extended valve front end which covers the gauge port in the tube and allows more airflow into the valve like I did on my .308/9mm build.... ;D
Bob
-
Yes, excellent! Lets see, doing it that way would give you a better flowing valve, and also allow the lower tube to come back another inch and half or two to get a little more air volume. Definitely for a Power Gun!
Bob, have you looked inside an Mrod valve for power mod options? Disco valve is .75 O.D., Mrod is 1.00. That's 78% more cross section. Hmmm...... sorry....... temporary diversion.... one thing at a time.
Lloyd

looks really cool lloyd. i'm sure many will like the added air. and the overall look of the gun and design looks nice. ;D ;D

lloyd
ur not helping me to keep focused on one project.. im tempted to start pondering a 25 disco, ur dual tube kit just opens to whole door to a world of projects that on the norm wouldnt be able to be done becuase the amount it would cost to have some do custom work like this. you are paving the way for awhole new level of airgunning
must stay focused on current project. just gotta keep telling myself that..now if i could just get the darn invoice for a certain part so i can pay for it and get it in my hands.....

Mike,
I agree, it is hard to stay focused on one project because of all the great ideas we see on this forum. The projects do take on an organic nature and change and evolve from their original concept. But I think they usually end up better because of it... or at least different.
Lloyd
-
lloyd
that is very very true, but as they evolve they are refined into safer better projects that end up as a finished product with most of the bugs worked out.. ive gone over my build so many times and it is very awesome to have a set course nailed down.
i think ur going to make a pretty penny or 2 with these dual airtube kits, but it will also allow others in the airgun world to see things they hadnt thought of. thus the evolution continues and it can only get better.. as i said i think you have paved the way for awhole new level for the airgun world.

Tom, are you describing a skeletonized airgun where instead of the tubes and action being cradled in the stock, you have a more minimalist group of parts attached to the action? Like a pack rifle with only enough "shaped " parts to give you something to grip?
I have wondered about the feasibility of a gun where there was a structural air tube that went almost from the muzzle all the way back to the butt, with a few slight contouring bends around the grip or cheek piece. It could have tremendous volume and still be fairly light weight. Using the normally accepted DOM hydraulic tubing would allow for some mild sculpting of the frame.

Mike, thank you for the kind words. I do appreciate them.
I always seem to be in the "development mode" and finalizing an airgun concept into a finished and executed and "pretty" design is something I don't do very often. I will have to get that satisfaction vicariously from the members with the creative and artistic ability to complete an attractive and balanced design. I think you have something coming along that will fill the bill.
Lloyd
-
I have a brand new .25 cal MRod valve, plus a poppet, sitting on my bench, I ordered them because I figured that it just MUST be better than a Disco valve.... Well, the exhaust port is TINY compared to a Disco, and so is the poppet.... so much so that I haven't even taken it apart to see what I could do with it.... I was thinking I might be able to borrow something for my Hayabusa project but I sincerely doubt it.... :(
I guess with 3000 psi available instead of 2000, Crosman decided they could get all the performance they needed without flowing much air.... It's interesting we see so little about hogging out MRod parts to increase the performance, isn't it?.... One thing I can see is that the wall of the valve is very thick because of location of the side mounting screws for the breech.... I guess one of these days I will get over my disappointment and actually pull the valve apart and measure it up.... ;D

ya there is a little something something in the works..lol..
like i said on the phone that night, i can look at a car for 10 seconds and then tell you what i would do to make it look like a show car. but i cannot for the life of me pick out clothes that make me look good.. we all have the things were good at, its when people come together with their own design skills that the magic really happens..
its eating at me not sharing the details of the project. but when its done it will be a show stopper

I think a lot of it is the cost of the Mrod plus the fact that it does so well out of the box. The disco is more abundant and easier to experiment on.

"Tom, are you describing a skeletonized airgun where instead of the tubes and action being cradled in the stock, you have a more minimalist group of parts attached to the action?"
When I built my disco conversion, I just ordered a 2400KT with 24" barrel and skeleton stock from Crosman Custom, then disco tube and necessities from Crosman and just swapped them over. Took about 30 minutes. Would take just 15 minutes to add your tube and the breech end of the tube would help protect the gauge which sticks down now. Then it would be easy to add a small forestock to the bottom of your tube clamp after it was slid closer to the breech. Regards, Tom
-
I was thinking gauge at very end of bottom tube.
Makes sense.... I forgot that the gauge was mounted in the upper tube.... Could you mount if in the lower tube (usual location) but without an adapter?....
Bob
-
Gene,
Gauge on one tube, fill adapter on the other?
-
Gauge on one tube, fill adapter on the other?
I think that might be just the ticket.... Maybe you could use the breech end to connect the tubes together at the old gauge port hole?.... just a thought.... By doing that, the front plugs on both tubes could be identical (threaded 1/8" NPT).... just use a band to keep them aligned....

Bob
I thought about that and there are compromises.
Gauge at front-
+ Bottom tube can be a little longer.
+ Custom stock wouldn't need a big gauge hole drilled in it.
+ others?
-gauge is bigger in dia than the tube, Cap for fill nipple would have to be special.
- Would have to deal with sealing pipe threads- might be an issue for some folks.
-Looking at the gauge means looking at the muzzle- Personally, that freaks me out.
Gauge in stock location-
+One less thing to mess with.
+ Matching caps at the front will give a finished look.
+ gauge is out of harms way.
- ??
Other considerations??
-
As a Disco mod (the whole point, right?).... I think the original gauge location makes the most sense.... simple, safe, and doesn't leave a big unused hole in the stock.... no argument.... My thoughts were directed more at the modded QB stock....
You have me tempted to mod my Grouse gun this way.... The tubes would be 2260 length (or slightly longer), 8-shot repeater riser breech, 2240 trigger group and skelton stock, 14.6" barrel with a full length shroud.... Set it up for about 25 FPE (18 gr. @ 800).... aim for 24 shots (3 clips).... Use a modded 2289 pump grip for the forestock like I do now.... Like this, but with another tube....

Bob

I'm moving my Disco fill nipples to the gauge holes and mounting the gauges up front on a high pressure Street 90, can read it from the left side and appliance mounting is much easier. If I was left handed, I would read from the right side. On the fill nipple in the gauge hole, if an adapter was made to fit at the top of the fill nipple threads, you could snap the black protective cover on, it goes a long way to filling the gauge hole and would stick out about .35" to grasp it.
Regards, Tom

Wow thats sharp ! Would love to have one like that.

Here is the disco action with the double tube kit, installed in the QB78 target stock. The air tube is stock length, but the .25 cal barrel, at 28", is 4" longer than stock.
I will have another install ready to show in a few days that will have some special features that I think you will like.
Lloyd
P.S. I am making progress on getting parts CNC machined.

Yep Lloyd this project is really coming along great. Can't wait to see what you have next to show us. And yes it does look like you just took it out of the box and laid it on floor for pics...:)
-
REALLY nice looking outfit Lloyd. I never thought of a QB stock for a Disco. May have to look into one of those. The matching end caps are a very nice touch. I'm guessing you CAN fill both tubes from either port or do you HAVE to fill each tube independently? My thoughts are for a .25, you will most definitely want a TKO or full shroud. Full shroud would require a little more routing of the stock and a larger barrel band. ;D
Just throwing around ideas, not trying to dampen the project. It looks FANTASTIC!!!!
Can't wait to get my hands on a kit.
Happy Shooting!!!!

I'm guessing you CAN fill both tubes from either port or do you HAVE to fill each tube independently? My thoughts are for a .25, you will most definitely want a TKO or full shroud. Full shroud would require a little more routing of the stock and a larger barrel band. ;D
Just throwing around ideas, not trying to dampen the project. It looks FANTASTIC!!!!
Can't wait to get my hands on a kit.
Happy Shooting!!!!

Hey Dave,
Please, yes, all constructive comments are welcome. I do want to get it right.
The top tube gets a new threaded end plug and a dummy end cap. The bottom tube gets a new one-piece threaded end plug and fill nipple and a matching end cap. There is a cross-over tube between the upper and lower tubes that is incorporated into the two new threaded end plugs. You only have to fill via the one fitting.
I have been thinking about barrel bands because there will be alot of different combinations required. The two 7/8" air tubes will always be the same, but the top barrel or shroud will likely be the big variable, in diameter and center distance. I have some ideas about that.
Another thing is something for carbine folks who want to shorten the pair of tubes. I will offer a shorter lower tube and then a service of shortening your upper tube. One thing is that, because of the front cross-over tube, both air tubes must be even (same length) at the front. Using a rear cross where the pressure gauge is would allow stepped lengths at the front, but is a little more complicated and costly.

Hi Lloyd
Something that just crossed my mind was about depingers. Do you think both tubes would require a depinger? I have been installing a 3" piece of vinyl tubing cutting it lengthwise to get the correct diameter for a nice snug fit in the airtube. A very simple easy way to take away all the ping in your PCP.

Norm,
Yes, I think as closely coupled as the two tubes are that they both might behave the same, but then again, the lower tube is nestled pretty well down in the stock. I think it would have to be shot outside with a shroud to really tell how much it needed a depinger in both tubes. It would be easy to slip one in by just removing the action from the stock.

yup, did the same thing to my disco a cuple of days ago really works to get rid of that ping

Here is the disco action with the double tube kit, installed in the QB78 target stock. The air tube is stock length, but the .25 cal barrel, at 28", is 4" longer than stock.
I will have another install ready to show in a few days that will have some special features that I think you will like.
Lloyd
P.S. I am making progress on getting parts CNC machined.

That looks rad. Its coming along nicely.
-
That looks sweet. Any plans on offering a ready to roll version ? Or how about a big bore version if the double tubes would support it.
Dave
-
Bigbore twin tube kit ? Maybe make the bottem tube the same size as a mrod tube for anything over .25cal.. should add a few shots for a 9mm or 308 build..
-
That is some beautifull work, I really like the way it looks in the Qb stock with the thinner band.
I sure would like to buy one when you are selling the kits. Even in the raw with a bed liner finish would work for me.
Are you starting a list of interested buyers? let us know llloyd ;D
-
degriz,
Yes, I have a list going and I just added your name. ;)
I am working on a website with pics and info and will have that up and running in about a week. I will PM people and have a link to it from here, also.
Plus, I will keep posting about it here, too.

Hello everyone,
I now have a website for the Disco Double kit. It will also be in the GTA Mall very shortly. That will give you a direct link to the website, which is:
www.airgunlab.com (http://www.airgunlab.com)
Take a look! My wife does nice work!
Thanks,
Lloyd
-
Nice site Loyd.
-
Very nice site lloyd, I think ur going to make a decent fairly consistant income from the sales
-
so whats the final price on this?
-
so whats the final price on this?
Sorry, but I don't have a "final" price yet. I am still working on the pricing for the CNC turning work and finishing. Sign up at the website (no obligation, of course)
www.airgunlab.com (http://www.airgunlab.com)
for all the info about the kit and look in the general FAQs for pricing. If you sign up for info on the website I will be able to send you an update when I finalize the price. It will fall between $100 and $195 depending on finishes and options, and I definitely want to keep the price as low as possible.

Lloyd now has his own Vendors Gate to discuss pricing and information regarging the new Disco Double. Please bookmark his Gate for all updates and information regarding the Disco Double.
Congratulations Lloyd

Just wanted to jump in and say nice web site. Your wife did a good job. Plus it is nice to see innovation at work.

Thanks everyone. My wife takes the website work seriously! And in doing it, she's become fairly knowledgeable about PCPs. ;)

great job loyd, the double tubeis awesome!!
your wife did a good job on the website too
maybe now you can get her into PCP's, youll have a good shooting partner!
-
have you tested it for 3000 psi yet, can it work on m rod. Nice site and great work

The Disco itself is not up to the 3000 psi task.
Please look at this thread for the reasons for sticking with the 2000 psi fill.
http://www.gatewaytoairguns.org/GTA/index.php/topic,25091.0.html (http://www.gatewaytoairguns.org/GTA/index.php/topic,25091.0.html)
I have tested the various parts and pieces of the kit to 3000 psi, though.
The Mrod has a different size tube. The concept will work, but this kit won't fit.

-
Very nice kit you have here. All these mods are making me want to get my disco all the more sooner. Can't wait to get the gun and install this kit. Keep up the good work.

Hi everyone,
Thanks very much for all the interest and comments about the double air tube setup for the Disco, the Disco Double kit. If you have any curiosity about the kit, please take a look at the thread listed below. I have posted some updated info there.
Thanks very much,
Lloyd

Awesome concept! I had the idea myself but not the talent to pull it off! LOL! Anyway I found your site and signed up for one (raw or unfinished if you please). Any plans for doing the same with the Marauder plateform?
Ray

Lloyd,
I have a couple of comments,
Great and simple idea on your part.
You cant Anodize chrome moly. You can only Anodize Aluminum.
I think you have a filler valve on the new tube. Why not just have a cap at the front end for possible cleaning purposes . Why not just a cap at both ends just to seal it . If the two tubes are connected together and the connection is sealed by O rings or some such method then you only need the one filler valve on the upper tube.
You will probably need a small spacer block between the two tubes so that the 2nd doesn't jam against the upper filler tube. This would mean welding the block on the lower new tube and contouring the upper surface of the block for a tight contact with the circumference of the upper tube.
This is starting to get difficult to manufacture. Maybe you could explain your idea further.

Nothing for the m-rod at this time. After the Disco is going well, there will be other things.

If Lloyd said to it must be true ;)
It is hard to argue with that logic.

My decision to buy a Disco was based on the upcoming availability of the double tube Lloyd...I'm excited over this and impressed that you and not Crossman, came up with this. They may end up making you an offer that you can't refuse but not before I get mine first please.
-
Jimmie lee,
Things are really starting to come together for the production of the Disco Double kit so have no fear that there will be one for you as things get rolling. Crosman has done a wonderful job of putting thousands of Discos out in the field, and like many of their products, the aftermarket loves them.
Lloyd
-
Lloyd, i've enjoyed my .22 disco as the first and only PCP rifle i own. Did field target with it last year and was a great, inexpensive platform to start on and couldn't agree more that it's becoming THE aftermarket in pcp for everyone.
Count me in on one of these awesome kits and i'll be back to shooting and tinkering with PCP again!
Simply designed with smooth and clean machining.
-
I wonder how many Benjamin Discovery's Crosman has sold? I bet we'd be shocked.
Lloyd
-
Judging by just the membership here, I'd say the sales have been huge across the board. Wally world couldn't keep them in stock for flying out the door there for awhile when you first brought this incredible idea to the airgun community and the prices for the Disco went back up and have stayed there. I bet we would be impressed with the amount of sales. I'd really like to hear something from Crossman on that end and they should give you a stipend for the renewed interest in these little jewels.

Really, the debt of thanks goes to Tom Gaylord, airgun guru and Blog master on the pyramyd air website.
https://www.pyramydair.com/blog/ (https://www.pyramydair.com/blog/)
Tom is a walking encyclopedia of airgun and firearm knowledge and one of the nicest gentleman you could ever meet, and anyone who has ever met Tom will agree. Always objective and honest, with boundless enthusiasm for airguns and airgunners.
Tom Gaylord is the man with the vision who originally brought the idea of the Benjamin Discovery, "an inexpensive, hand pumpable PCP, based on the 22xx series", to Crosman, and the rest is history. Everyone else, including me, is just riding on Tom's coat tails.
I certainly owe Tom a debt of gratitude, in fact I think many of us do, because if it weren't for him, the PCP world might still be out of financial reach of most of us.
Tom, my hat is off to you!

This mod is what I have been been waiting for, and the excuse to get a light PCP like the Disco. I got spoiled with the low-mid power shot count# from my Condors that come with a 500cc bottle, so it was hard for me to get a Disco before. I am definitely reconsidering that now.
Is the final product (double-air tube and associated parts), fully tested and available now?
Harry
-
yup, all that i think is being waiting on is cera kote finishing on the tube if you want it.. but as of now the disco doubles are able to be bought, 99% sure of that..
if you want to buy a disco set it up with using the pyramydair.com live chat so i can make a in chat sale and some points

Harry,
Yes, there are many of the production versions out in the field now and the feedback to me has been positive. I now have the Cerakote finish squared away, or you can have it unpainted if you want.
Also have barrel bands for the stock configuration and for the BNM multishot breech. Some folks have wanted a carbine version so I've shortened their barrels and tubes.
If you want something a little different, please ask.

If you own a Disco or thinking of getting a Disco and want to mod it, This is in my opinion the FIRST and probably best thing you can buy for the gun...
