Description
- Hybrid 3D printed ASA and steel construction.
- Used for adding a 6-position AR buttstock to the 1377, 1322, 2289
- Polymer tube reinforced with steel bolt threaded into steel adapter
This kit includes everything you need to convert your Crosman 1377 or 1322 into a custom carbine. The kit includes a 4140 steel machined black-oxide coated adapter, 3d printed "buffer tube", and bolt. The stock can quickly be adjusted from an 11" to 14-3/4" length-of-pull. The buffer tube is 3d printed in ASA. It is attached to the airgun with a machined steel adapter and reinforced with a 1/4-20 X 6-inch bolt. It is made to MILSPEC dimensions. We highly recommend Magpul buttstocks for this extension tube, but it is compatible with any MILSPEC AR adjustable buttstock. This is compatible with a stock 1377, 1322, or 2289 with or without a steel breech. Note that you will no longer be able to use the stock iron sights with this stock. If you have a steel breech, I recommend you use a scope with tall scope rings. PLEASE NOTE: If you cannot get the screws to align with the screw holes in the adapter, you may need to remove the buttstock and loosen the long bolt that goes through the stock tube, reinsert the steel adapter, install the stock screws, then retighten the long bolt. This item will not work with power adjusters or rear cocking handles!

Installed on a Crosman 362 that was built with upgraded internals, long steel breech, and 13xx lower by alchemyairwerks.com. It will dump all the air from 12 pumps. The pump tube diameter for the 362 is the same as the 1322. Much better eye alignment with the scope compared to the OEM Backpacker stock and it doesn't wiggle. The minimalist stock assembly weighs approximately one ounce less than the OEM Backpacker stock.
Easy to install and some of the nicest printing I've seen. Fits my 1377 and the collapsible brace I had perfectly with no wobble. Buck-rail products let me customize my builds at an affordable price without sacrificing quality.
This is my 3rd time buying and Installing this Great Adj 1377 Stock ! There is nothing else to Compare! It’s a Must for all 1377 and 1322 pistols ! Again Many Thanks to Terry !
Replaced side folder with straight shoulder stock. Good solid product as are all the things I've bought here.
Wow , This really works and makes other Stock Obsolete ! Everyone deserves to buy one or two of this Rock Solid Stocks ! Thanks Again to Terry for making so many Great Products!
Well, built, but a little straight out of the pistol. It's hard to get a good site picture out of a scope.
The minimalist buttstock makes it easier to balance the gun and aim with a much more relaxed posture, steady position and precision on the target for more consistent targeted shots in the bullseye. Target set at 22 yards and hitting the bull at times with groupings of about 1 inch.
I did a sniper conversion on a Crosman 2289 Drifter. 24" barrel integrally suppressed, AR-15 pistol grips, longer pump arm, and upgraded internals built by a friend of mine for an average of 820 fps with 14.5 gr lead pellets. Only problem was that the stock wouldn't allow a proper cheek weld that lined my eye up with the scope. I bought the adapter and added a stock with an adjustable length of pull and cheek riser. The faux buffer tube adapter by Buck Rail is solid, sturdy, and built to last. It's a very easy install. Love Buck Rail!
Easy mounting and it works good. If I were to make a suggestion would be to make the stock on an angle to allow shooter to use iron sights. The way it is built you must have another site type that mounts above the barrel.

I have purchased one for 1322 and one for 1377. Milspec stocks fit securely and they look great. Takes shooting to another level. Great product.
