Barrett M107A1 S .50 BMG Semi-Automatic Rifle — Flat Dark Earth, 29-Inch Fluted Barrel, 10+1
The Barrett M107A1 S is the modernized, lighter successor to the iconic M107, chambered in hard-hitting .50 BMG. Finished in Flat Dark Earth Cerakote, this semi-automatic rifle combines a 29-inch fluted, chrome-lined barrel with a suppressor-ready three-port muzzle brake, a full-length 27-MOA Picatinny rail, and Barrett’s lightweight titanium bipod assembly. Four pounds lighter than the legacy model, it delivers the strength of a steel upper, the weight savings of an aluminum lower, and a skeletonized stock with an adjustable rear monopod—all engineered to enhance long-range capability while easing carry and deployment.

At the heart of the M107A1 S is a short-recoil, rotating-bolt action tuned for reliable semi-automatic fire with the powerful .50 BMG cartridge. The rifle’s 29-inch chrome-lined barrel is fluted to manage weight and heat while extending barrel life.
A 23-inch, 27-MOA Picatinny top rail runs the full length of the upper receiver, providing ample mounting real estate for day optics, night-vision devices, or other mission-driven accessories. Flip-up IS-3 pattern iron sights, graduated to 1,500 meters, fold flat when not in use.
The suppressor-ready three-port muzzle brake tames recoil and threads directly to accept the Barrett QDL suppressor (not included). Combined with a 1:15 RH twist rate, it helps deliver consistent accuracy with a wide spectrum of .50 BMG loads.
An FDE Cerakoted steel upper receiver mates to a lightweight aluminum lower, and the skeletonized stock houses an adjustable rear monopod for fine elevation control. The titanium bipod legs lock solidly yet detach quickly for transport.
User-centric features include an ambidextrous lever safety, a 15-inch length of pull, and a black polymer AR-type pistol grip. The rifle ships with one 10-round steel magazine and a rugged Pelican case—ready for duty, competition, or collection.
