Bushmaster M4 Built Complete AR15 Lower Receiver - Black | BFI M4 Carbine Stock | BFS III Trigger Equipped

The BFSIII® Built Lower Receiver, the perfect addition to your firearm collection. Crafted with precision and built for performance, this lower receiver boasts a weight of just 2 LBS and a range of impressive features.

Constructed from a 7075 Forged XM15-E2S™ Lower Receiver, this receiver is designed to withstand the toughest of conditions. The 6 Position Buffer Tube and M4 Carbine Stock offer a comfortable shooting experience, while the A2 Pistol Grip ensures a firm grip on your firearm at all times.

In terms of safety, the BFSIII® Built Lower Receiver comes with a Mil-Spec Trigger Guard, as well as a BFSIII® AR-C1 Trigger and BFSIII® Ambi-Safety Selector. With three trigger positions - Safe, Semi, and Binary - you have complete control over your shooting experience. In binary mode, the trigger fires one round on the pull and one on the release of the trigger, with the second round being cancellable via the safety selector. In semi-automatic mode only one round is fired per pull, and in safe mode the gun will not fire.

Please note that the BFSIII® trigger is not available for civilian sales in CA, DC, IA, NJ, NY, HI, DE, RI, FL, MD, CT, or WA.
