Re: CMMMG Upper
Darin,
I bought the med con barrel that had a tight chamber... it kept popping primers out... I could pretty much get it to do it at will... by running 10 or more rounds pretty rapidly through it. I sent it back,,, they said nothing was wrong with it and sent it back to me. I tried again and the same thing... still popping primers... so finally they re-funded me my money. Really no big deal other than a super pain in the rear. Can everybody make a lemon now and again... absolutely.... but....There are just too many choices out there to deal with that. With LMT, Sabre, Colt, and some of the custom builders like Denny at Global tactical being at the top of my list now.
Hope that helps.
Dale
