And another friendly BUMP!
Just finished this build. I like to think of it as the “AR15-A5.”
Materials list:
Aero slick upper. Larue LAT handguard. Magpul Mlok rail covers. Surefire M300 on SF mount. BFG sling. Criterion chrome-lined 16” pencil barrel with FSB pinned by RAW. A2 FH. Daniel Defense fixed rear sight. Microbest chrome BCG. Aimpoint Duty RDS on Scalarworks mount. JP Enterprises silent captured spring. Radian charging handle. KP15 lower with Larue MBT trigger. Might eventually add a magnifier.
Weight without mag (but otherwise exactly as pictured) is 7 pounds even. For comparison, my Colt 6720 with factory furniture, but with the same sling, light, and optic is 6 pounds, 15 ounces. Basically the KP15+slick upper weight savings allowed me to trade up to a stout free-float HG for a 1oz weight penalty. And the Larue is not even the lightest available, but at the time it was by far the cheapest at $90. The weight would probably be in favor of this build over the 6720 if I used a standard spring&buffer, as the JPSCS adds a couple of ounces net. I’m very happy with it so far. Need to go shooting next week!
