When reassembling the bolt/carrier/firing pin...make sure the firing pin retaining pin is on the proper side of said firing pin. Made that mistake a couple times in boot camp and when we all went to present arms, the only sound was of a tiny clinking firing pin falling from the bolt carrier, and the hoarshest whisper I've ever heard a D.I. "whisper".
