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, bolt, and adjustable buttstock.

The stock can quickly be adjusted from an 11″ 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.

This is compatible with a stock 1377 or 1322 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. Both of our scopes come with these. Our Picatinny mounts with a Red Dot is a perfect combination with this stock.

Choose “without buttstock” when adding to your cart if you don’t want the buttstock included in this kit.

I will make an installation video soon. For now, installation is EXACTLY the same as the 2240 stock kit.

    Just received this in the mail today and installed it, It’s Awesome and a must buy if you have a 1377 or 1322 American Classic, Great Quality/Craftsmanship, makes the air rifle look like a AR platform with the buttstock! I’ve purchased alot of custom parts here for the air rifle/pistols listed and always impressed of design and quality!

    Love it! Easy to install, much sturdier than I was expecting. This plus the larger forearm makes it much more enjoyable to shoot. I got my 1322 from the custom shop so I’m having to buy grips elsewhere. Wish I could have gotten them here. A stock/forearm/grips package would be a nice combo. Awesome product. What next to buy, hmmm…..

    Was like a kid on Christmas when I saw this available. Bought without thinking twice.
    So glad I did. It’s everything I ever thought an adjustable stock for the 13xx would be.
    Easy to install and so comfortable with the butt pad.
    Quality design and construction. Such a super cool upgrade for these.

    Another must have, I was super surprised 😮 that it shipped the same day I ordered it, this collapsible stock helps with tightening up groups and makes it easier for the grandkids to shoot, another product that I am glad to say I ordered from buck-rail, thanks for great products and for your service sir
