Do you need to check headspace with the milspec BCG? I am hearing conflicting stories, but most are saying as long as it's high quality you don't. Just trying to get it right the first time, guys at CGN seem to generally know what's what.
I have never checked headspace on an AR15 and i would hazard a WAG that 99% of people who own one or have replaced a bolt haven't either.
Should you? Maybe, but generally it's a non-issue.
