| The bolts on all of my uppers are hanging up on my registered SBR lower(CMMG). I tried switching the buffer retaining pin AND switching the stock out. I've tried multiple uppers and different bolts. I'm really hurting because I had faith enough in CMMG(not saying that I still don't) to register one of their lowers. I NEED to get this fixed bad. I'm in NE Kansas and I know CMMG is in MO but I don't want to have to drive all the way there. HALP!!! |
