Snatched this NIB BCM upper on gunbroker.com for under retail! I lucked out considering I still see this exact upper going for $800+. Anyway I wanted to see what all this BCM hype is about. It is a mid-length 16" w/ centurion C4 12" ff rail. I opted not to go with the BFH because after reading the "filthy 14" article, why would I need a BFH barrel when I know for a fact I wont be going through 40-50k rounds in a 2 year span? I mounted it to a spare receiver I had and threw on a bunch of parts. The BCG is an extra I had laying around. Will put in a BCM BCG when I find one for under $300. KAC VFG Moe+ grip B5 Sopmod Spike's 7075 buffer extension Troy folding sight set KNS anti-rotation pins IKH Slap plate Will complete this gun sometime during the summer.
