I recently installed an APS2 cylinder into my G-22, and now my gun will sporadically lock back, but most of the time it simply doesn't lock, allowing the spring to decompress as the bolt slides back forward.
It just wont cock. Every once in a while, I will be able to fire three or four shots before it starts acting up again.
I have seen this topic on some other forums, but no actual helpful information was given to the other victims. Nearly nothing on the gun is stock.
What is going on?
