The Barrett M107A1 .50 BMG Semi-Auto Rifle (Barrett part no. 18065) pairs Barrett’s proven recoil-operated big-bore action with a longer, fluted 29-inch barrel finished in black for improved heat dissipation and a distinctive look against its Flat Dark Earth Cerakote furniture. Built by Barrett Firearms, this variant is suited to shooters who want the extra velocity and stability a longer tube provides for serious long-range .50 BMG work. The 1:15 twist rate keeps heavy .50-caliber projectiles stable well past typical rifle distances, and the 10-round magazine capacity means fewer reloads between strings of fire. It’s a rifle built for dedicated long-range shooters, whether that’s precision work at the range or serious field applications. Adjustable back-up iron sights are included standard for a dependable zero at all times.
