Was doing a cheaper 11.5 ranger build with the one that had the black rail. Low round count on everything and mostly new. It’s a colt cage code receiver, giessele airborne ch, mk16 10.5 rail, rosco 11.5 barrel with Bcm block and tube. Has the Bcm kag grip, 5,7 slot mlok sections. And an arisaka inline scout mount. And a direct thread mount for a hub can. It was rocksetted and I don’t want to deal with it so it comes with! Looking to trade for a 14.5 socom m4 upper. Just the basic bitch m4 upper.
