Title: Improving the stock on a Benjamin Maximus
Post by: Krawdad48 on August 07, 2021, 08:32:58 PM
Hi,

First time posting, so hopefully this goes well. I am looking to improve the stock on my Maximus.

I have searched through all the forums here and other airgun forum websites.  So I have a  seen posts from people who have done this and I have a pretty good idea about some of my options. Just wondering if anyone minds giving their thoughts on these ideas?

First thing I am considering is just removing the butt plate on the factory stock and filling it with something like expanding foam to reduce the reverb/echo when firing.  Just not sure how effective this will be, but it would be the quickest and cheapest route.  I'd also look into a proper rubber butt pad rather than the cheap and slippery plastic one that comes on the factory stock. I assume the butt pad just pops off, as I don't see any screws holding in place.

Second idea is a Boyds aftermarket stock.  I realize they make the stock for the Benjamin Discovery but it's my understanding that it should fit the Maximus. However, I also understand the factory Discovery stock screw is shorter than the factory Maximus stock screw.  So I am wondering if someone who has put a Boyds stock on a Maximus can tell me which screw they used? If the longer Maximus screw is too long, can washers be placed on the screw to take up the slack? I realize this is probably over kill fir such an inexpensive airgun, but I rather like tinkering with airguns.  I have a 1322 that has a ton of upgrades just because it's fun to see what can be done to improve it.

Thanks in advance for any thoughts and advise,
Dave

My G2 Fortitude has that same slippery butt, so I got one of these and it works great for me.  There are other brands too; I got this one since it was on sale ;)

I would personally go with the Boyd’s stock. I literally bought my Maximus because I wanted to upgrade it with Boyd’s stock but I hate the gun too much to waste the money Lol. Only gun I have that I completely regret buying.

Boyds has its own screw that goes with the gun.

It is a countersunk allen screw to fit their stocks with a delrin escutcheon or built-in, non-removable washer with a beveled hole.

I replaced mine with a stainless one from Ace Hardware.

You should not worry about those ubiquitous screws, just saying.

Boyd’s inletting is lousy/loose—I shimmed mine.

The Disco’s/2260’s inletting is much more superior, really.

I would have to agree that the Maximus isn't a premium rifle.   ;D. I am glad it is priced so low because I find adding modifcations is fun and I would not want to mess around with a really expensive airgun.

I think I will try filling the factory stock before laying out money for the Boyds,  but I did want to reach out to the great and knowledgeable group on this forum and get some thoughts.

Definitely something the factory stock needs.  Such a shame they didn't even put a rubber pad on the factory stock.

Wow! That blue laminate is one of my favorite choices in a laminate stock

It looks like you did a few modifications there.   ;D

I shimmed the sides (where the trigger assembly goes in) with a thin plastic card---the strips are not visible.

The shims rid the side to side looseness.

Now, the action would still teeter toter, so I laid 2 unscathed and suitable O-rings around the barrel channel and a cut O-ring in the rear section--the cut O-ring cradles or presses against the tube's rear cap.

Post these simple mods, my rig is now super solid.

My thought if wanting to save some $ 2260 stock, will need an air gage hole bored out but fitment is better.
I put one of my Maxis in a more solid with rubber but pad Synthetic QB stock still have to remove some internal plastic, and a gage hole optional, but makes reading it easier. Cheaper than a Boyd's, and you get more spare airguns parts to play with :)

I put the QB action in an old 1400 stock.

It is a low power PROD with a 1701P tube.

The PROD's gauge hole does not align with the Boyd's gauge hole, hence I replaced it.

Trigger assembly is an all-metal Magnum Air Power for the Disco.

Yes, it is Cerakoted in silver.

Scope is a Japanese Clearidge RM.

Stuffing the stock will quiet the hollow noise down.  I did it on Maximus/Fortitude stocks, as well as mrod.  I used packing peanuts, and crammed in as many as I could, which is easier to remove, some time in the future.  The pad comes off after removing the sling stud.

The lop is short for me, so use a slip on like was already posted.  I run the sling stud through it. 

As mentioned, Boyd’s comes with its own stock lug.

I lucked out on the Crosman barrel lottery with Maxine, and I really like the 2,000 psi fill pressure when hand pumping.
I can concur with Rick, the Boyds "Evolution" stock came with it's own screw and the inletting was a little large.
 I solved that problem with the felt side of some 1" wide velcro.

Oh man, thats awesome. I was wondering if there was a trick to remove the buttpad.  I figured the pad must be either glued in or snapped in as well as the swivel stud.

The packing peanuts are a good idea too, rather than spraying foam into the stock.

Thanks a million!

I would like to have two of these. One in a camo color scheme, because it looks like it would make a fine tight quarters, bush airgun.  And another one in a beautiful color combination like yours.

That setup almost looks like it's made for a drop block and bottle or a second tube.

I just can not bond with the Maximus stock...not a fan of Syn Stocks anyways... Max Maximus wears  Grandpa's American Elm stock & Magpul RLS sling... I have two more 160 stocks inleted and almost ready for my other 2 Maximi...

The Qb 78 Stock can be used also...   https://www.gatewaytoairguns.org/GTA/index.php?topic=82285.0 (https://www.gatewaytoairguns.org/GTA/index.php?topic=82285.0)

I believe the sling stud needs to be removed before removing the butt plate.

would look good in a Boyds Rimfire in nutmeg... pic in post #27(with Fort but Max and disco fit)...

I really like the 160 stock... about 60 years old (only steamed most dents) shows some of it's history... the swivels indicate there is a chance it is from an Air Force training 160...because of Dutch elm disease  American Elm is an endangered species...it is also an excellent stock wood... IMHO... the interlocking grain make for a wrist that is less likely to split... Density is very close to that of walnut...

In fact A. Elm is known for being a  hard wood to split...https://firewoodhoardersclub.com/forums/threads/hand-splitting-elm-the-easy-way.30377/ (https://firewoodhoardersclub.com/forums/threads/hand-splitting-elm-the-easy-way.30377/) 

That link was to show the interlocking of the grain...

But speaking of the wrist that is what I like least about the Maximus stock...it positions my trigger finger towards the joint rather than the pad... have to consciously avoid that...
it look like it might be the somewhat the case with the Boyd's stock also...

 If you look at the 160 it is just slightly longer wrist to trigger and it positions on the pad very naturally...this is using the 160 stock lug hole to locate things when you modify the inletting for the Max trigger pack...when shouldered the 160 is close enough to feel of the Remmy 512 stock  I grew up with that it just feels right... the inletting for a barrel band is already there at the muzzle end of the stock... did need to deepen and widen slightly... so yep am happy with my choice of stock... could not have been better suited to me if I had planned it.. ;)

If you go the expanding foam route, there is a denser variety of it available from the common vendor (who I cnt think of right now). Use it, itll kill more of the hollow sound

Also, tape off anything you dont want foam on, cover the stockin a plastic garbage bag, and wear gloves. Oh, and do the foaming thing somewhere you dont mind foam getting on

And maybe TBL the stock after the foam treatment

Post by: K.O. on August 11, 2021, 01:16:02 PM
TBL..?

Trash Basket Locate..?

oh wait there is a a hardware store trip for the foam so must be truck bed liner...

hollow it does  have room for some survival stuff...flint n steel hooks and line...so if could deaden sound and retain most of the space that would be optimum for my taste..

I had a slightly different take on the Maximus stock and the Maxi in general.  I was not to partial to the very long air tube and barrel, so I cut them down and re-threaded them.  I realize that is where it gets the shot count from with the 2k psi fill, and the velocity with the extra long barrel, but to me, in the woods, all that extra length was difficult to move around with.  I also did not care for the 'schnable end' on the stock as well as the hollow 'ping', so I lopped off the front end and filled the voids with epoxy with carbon dust in it to make it blend in a bit.  I also filled the stock with deadening foam, like the stuff that protects products in those fancy waterproof cases.   Sadly despite prepping the surface of the plastic stock cut pretty well with 80 grit, the epoxy still had an issue getting a good bond.  The stock looks good from a few feet away, but under close examination, the cracks where the bond leg go, can be seen.  I did buy a Boyds Barracuda stock that I intended to put on this Maxi, BUT I also have a Disco I intend to put together from parts that needs a stock, so the Maxi will probably keep the plastic stock.


The result is a handy, maneuverable, woods hunting carbine, that is light and the looks (in my opinion) are slightly improved (pic before a scope was installed).



Airguns are what they are, and if they are not, modify it to your liking. ;)

PS. Oh, and the 'muzzle thread protector' was a bit of a goof on the airsoft rules since my kid is into airsoft.

Well I must say I don't mind the Schnabel forend, but that's just me. Haha.

Having said that, chopping it off in the manner you have does look ALOT better and it does look like a nice handy carbine.

Its also a shame they put a smooth plastic butt "pad" on this rifle.  Not even grooved for any grip. Cutting costs is one thing but come on.

It was mentioned the cheap plastic butt pad comes off but the rear sling swivel stud needs to be removed first.

Is the plastic butt pad clipped in or glued in as well?

I have to say, its fun modding these airguns!

Thanks,
Dave
