My buddy just bought a S&W M&P 15A. When I broke it down for him, I noticed that the bolt carrier was only a semi and the bolt had a forge mark of a “T” encircled. Also, Pmags didnt lock up :mad:
I already knew that the Pmags might not work but I thought that S&W shipped with auto BCG by LMT (or is the “T” their forge mark)
