Gentlemen:
I recently have had a pre-ban Colt upper, without the BCG, come into my possession. In your considered opinion, will I need to do a head space evaluation (removing the ejector, etc.) on any new BCG I obtain before going forward and completing this project? This is my second AR build. The upper for the first build was completed so no problem. Any suggestions/ assistance would be appreciated.
