FBM Half *** issue
Hey guys so I have an Fbm half *** and just picked up a ccm half block lower tube kit since the wgp lowers I had were beat to hell and needed replacing. Now The issue I'm having is that the gun won't cock when I pump it. I've tried adjusting the lug and it seems that the slot is milled too far back for the pin to push it back far enough. I threw my wgp hammer back in for now but I'd really like to use the ccm, so is there anything I can do?
