Cobalt Kinetics Pro Series 5.56 NATO Barreled AR-15 Upper Receiver - 16"

Cobalt Kinetics Pro Series 5.56 NATO Barreled  AR-15 Upper is built to exceed even the most demanding needs of AR builders and high-volume shooters. This 16-inch barrel upper is expertly designed to preserve accuracy with its properly seated 4-point mounting system that locks the free-float handguard into the upper and barrel nut that features extreme engagement with the melonited 4150 CMV barrel so that it stays put. Cobalt Kinetics also includes the RCB 2.0 muzzle device that not only looks cool but also serves to mitigate muzzle flash and to keep the gun flat while shooting, so you can be sure to make accurate follow-up shots. All you need to hit the range with this upper is a BCG, a charging handle, and an optic. This upper's 16" barrel makes for a perfect do-all style rifle build that can reach out to distance but still be maneuverable.
