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.

Thanks for lookin’ y’all!

    Outstanding ! ,and 1/2rd of the cost for a Tippman stock and mount from the UK.

    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!

    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.

    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!

    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!

    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.
