I'm building my recently anodized 80% lower and mating it up to a M4 Enhanced upper from Aero Precision. I'm running into a couple problems. First, the build.
Lower went together okay. The issue I ran into was that I put the barrel in and it has a little retaining ball on it and I can't get it out of the upper. It seems to be attached to the BCG. Any ideas on how to remove it?
