Description
- Hybrid 3D printed ASA and steel construction.
- Used for adding a 6-position AR buttstock to the 2240 or 2240XL
- 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 -20 X 6inch 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 2240 or 2240XL. 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!

A great addition to the 2240 making it an air gun SBR. It’s a solid quality product. The shipping is fast. Go ahead and order the suppressor also to complete the build!
Great site and item description. Fast delivery and quality products.
This is another product that has exceeded my expectations.
Another purchase I'm highly satisfied with, prompt shipping is always a plus! 5 stars everytime!
The fixed stock tube on my 2240 PCP is the perfect addition to my mods. 2240 Suppressor, Safepac by Froggy, 14.5 match barrel, walnut pistol grip, minimalist stock and Aimpoint red dot.... + More. Thanks again. Merry Christmas and a Happy New Year 2024!
stock still adjusts to small/short shaft should be longer for guys with long arms
I'm very pleased with the stock and the service.
I couldn't ask for better!!!
Great quality easy installation perfect fit. Been using the crossman stock on this for a few years and it was ok but with the new adjustable stock it is more comfortable.

Solidly built and very easy to attach to my 1377. Worked fine with a MAGPUL AR stock.
Things I Would Have ChangedNothing
What Others Should KnowEarlier I changed out the two screws you must remove to button head ss screws that required an Allen wrench. I think this may have made assembly easier. I also had some problems acquiring an adjustable AR stock through a well known sporting goods chain due to restrictive laws in MD pertaining to AR attachments but avoid this by trying a different store.
