Had this BCG for a few weeks now. I went thru it gauging everything before I ran it. Only flaw I found was the pocket that holds the extractor spring was a bit wide. That's a non issue really. Over 30 different gauge points all passed. BCG has ran flawless in my 24in comp build. Well done and would definitely recommend RCA to look at for your next builds or replacements.
