While you’re in there, see if there’s any way to add a recoil buffer. Anything that might soften that bolt slamming against the receiver.Other than the bolt moving back and forth, the Airsoft M1A1 is not the same as the Umarex Co2 BB gun. I am going to have to take apart, at least partially, the Umarex lower to expose the bolt mechanism (very carefully) and hopefully have access to the spring/bolt mechanism and see what is what. It is after all a C02 BB gun and not a Swiss Watch or nuclear reactor. (Taking pictures as I go.)
