When the Crossman custom shop was open I ordered a small light weight rifle with a walther barrel, camo stock, match trigger. It's CO2. I thit was based on the 2240.
Stupid accurate at 20yrds. But doesn't have the power to kill anything but a bird at 7fpe. It was for my 7 year old. my other ex-Co2 was a Hammereli 850. Walther barrel again. I got it for my wife. She out shoots everyone with it to the point you get pissed off and just quit. I converted to a large CO2 tank and it would go 400 rounds till low. But only 13FPE.
I converted it to HPA and set the reg at 1800psi, 2 stage trigger mod, hammer spring, and polished slide hammer. 26.5fpe now. Not a fan of C02 anymore. Would rather have HPA.
