14.5" "Enhanced Light Weight" tapered barrel with the BCM 13" "KeyMod Rail" Upper Receiver Group.
Well the "Little Brown Truck" arrived today bearing gifts. I still need a couple more things to finish my Mega lower build so I slapped it on my M&P lower to see how it handles. Man is there ever a difference in weight. So I still need to finish the lower, get some rail panel, a light, and a set of folding BUIS. Sorry for the ****** cell phone pics.
