This kit includes everything you need to convert your Crosman 2240 or 2240XL into a custom carbine. The kit includes a 4140 steel machined black-oxide coated adapter, bolt, washer, and adjustable buttstock.  It does not include the scope, silencer, or bipod pictured above.

The stock can quickly be adjusted from a 10-3/4″ to 14-3/4″ length-of-pull. The buffer tube is 3d printed in ABS by a veteran-owned business in the USA. The adapter is machined by an American manufacturer. The adjustable stock is sourced from a Chinese manufacturer, but is of very high quality for the price. My 6 year old son shoots dime-sized groups at 15 yrds with this stock combined with the Dr. Murfee mount and Bipod.

Choose “without buttstock” when adding to your cart if you don’t want the buttstock included in this kit. The buffer tube is compatible with MILSPEC buttstocks.

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.

Thanks for lookin’ y’all!

    I have a Crosman 2240 and I bought not only the simplified buttstock but also a suppressor and I found a six-shot gravity-fed MAG from another website but they fit perfectly together with the parts that I bought from this man’s website not only does it make me feel good to contribute to American company but also to a veteran by removing the flow regulator and a few other components this came out to look like a pretty sweet and also very powerful 22 carbine

    If you’re putting a stock on your 2240 then this is the only stock you should be buying.
    Parts are high quality and the instructional video makes it child’s play to attach
    Five stars is underrating this product, It deserves ten.
    Thank you

    Just installed the standard kit on my 2400 pistol- making it a nice carbine. Fit and finish are perfect on the parts. Thanks! Please keep the awesome parts coming!

    Very comfortable & easy to install (despite that pesky square head from Crosman) – great work and really does make a 2240 more fun! Thanks for the good work!

  5. Tynan Whitby (verified owner)

    Install was easy and enhances the usability of the 2240. Like Terry said in the video high scope mounts are needed.

    Satisfied. Out of all the AR stock designs, yours fit the look I was after. I was unhappy with the crosman stock ’cause I noticed play in it after mounting. This one is tight, sleek and fits the gun. If you ever decide to do a milled aluminum verision of your buffer tube I’d be interested. Until then this works.

    Excellent tight fit. Been looking for a better stock for my 2240 than the o.k. crosman one. Easy to assemble. Easy to adjust for different size people. Quality, price, and easy to install, not much more you need than that.

    Took me about five minutes to figure it out, couldn’t play the video on my phone but it worked on my laptop. Great part. Well made and easy to install, glad there’s guys out there to build stuff that doesn’t cost an arm and a leg to add parts to our airguns. Thanks so much!

    I just got this in the mail a few days ago and it is the PERFECT addition to my new Crosman 2240XL plus I ordered the 1/2 UNF silencer for it tonight which will transform my 2240XL into a nice .22 carbine. I’ll complete the build once Terry gets the 2-6×32 SOEG scopes back in stock. I can’t wait to see what Buck-Rail comes up with next. Thanks and keep up the good work!

    Same as with the 1322 pumper arm, I got this a few weeks ago, and just got around to installing it on a brand new 2240XL. Love it, love it , love it! Mounting it was a walk in the park. Well built, and thought out. Your work is amazing. I have not shot it yet, as I still need to choose a scope, or red dot of some type. But just shouldering it tells me it is right where it needs to be.

    This stock kit is another home run! Just what I was needing to round out the build, for now..
    Be aware that you’re going to need high rise rings if you plan on running a scope. I swapped out the original crosman stock which has a much lower comb. The kit includes a small checkered cover piece for the stock if you’d prefer to remove the rubberized butt plate.
    BONUS: there is an ambidextrous female qd receiver for a single point sling built into the stock. This is perfect because I already have this setup for my reign and urban, plug n play!
