Crosman 1377 and 1322 Adjustable Stocks

Crosman 1377/1322 Adjustable Stocks Are Here!


These have been in the works for a while now and they’re finally here. I’ve had a lot of fun with the P-Rod and 2240 stocks. They make for a great addition to both of those airguns, but these take the 13XX to a whole other level. The carbine pictured above is my lightly modified 1322. I’ve installed the adjustable stock, picatinny mounts, reflex sight, extended crosman barrel, our Plumper Pumper, custom 3d printed barrel band(coming soon), and slip-on suppressor. It’s been a blast “testing” this thing out.

This kit is much like the Crosman 2240 kit, but with a different adapter and slightly different buffer tube. You’ll not be able to use the stock iron sights with this stock installed. However, I’ll try out some different flip-up “iron” sights with our picatinny mounts to see if I can find a good option for folks who want the adjustable stock while still utilizing open sights.

There’s a lot more stuff in the works. Stay tuned.

  1. Is your buffer tube milspec or commercial diameter?

    1. I used Mil-Spec 1.145″ for the buffer tube diameter. Tolerances aren’t super tight though compared to a machined part.

  2. Plumper pumper installed on your tester too?

    1. Yes! I just updated the post. Noticed I left out the link and posted a really crappy picture as well. Just replaced it with a less crappy picture and posted the link. Thanks for the help!
