Title: Crosman 760 5th variant .22 carbine
Post by: happymecanic on July 28, 2023, 12:29:54 AM
Actually quite a frankengun lol! Butt stock, metal receiver and trigger mech from a 5th variant 760. Barrel is a 15'' left over piece of a 24'' Crosman 2260 .22 barrel I bought a while ago, machined to fit a plastic barrel support/breech. Compression tube from a M4-177. The piston and valve are bone stock 760 stuff. I cut off the stock probe off the cocking block and made a new Oringed, open bottom, flow-through bolt probe, and machined the pellet channel in the receiver to 1/4''. I get a max of 491 fps with 11.9 GR Hobbys, and 463 fps with CPUM 14.3 grains. I use a UTG 3-12x32 AO SF scope on the gun, perfectly balanced for its size. I also added a small steel muzzle brake to complement the package, and a 13xx forearm to slim the rifle's line down a bit. The gun is very nimble, only 32'' long. Hope you like the view!

 The slim pump handle gives it that old school carbine look.  8)

That's pretty much what I was looking for, love that look ;)

Cheers!

Nice bolt mod.

I had done something similar, with magnet removed, for my 1978 760 mod with 66 comp tube and Lothar Walther barrel. I added an O-ring seal between the barrel and support though.

Very cool. I have my Coleman era 760 still, it's been resealed and a 2100 barrel installed. I've given thought to converting it to 22, yours tells me it's worth doing. Down the road, I have enough projects for now.
