The Barrett M107A1 .50 BMG Suppressor-Ready Semi-Auto Rifle (Barrett part no. 18066) brings the same suppressor-ready engineering as Barrett’s other M107A1 variants, wrapped in a Flat Dark Earth Cerakote finish with a fixed stock, Sorbothane recoil pad, and black polymer grip. Built by Barrett Firearms, it uses a redesigned bolt carrier group and a four-port steel muzzle brake engineered specifically for the quick-attach Barrett QDL Suppressor, shaving roughly 5 lbs off the original M107 without giving up reliability. The lightweight aluminum upper receiver includes an integrated 27 MOA optics rail, and the 20-inch, chrome-lined barrel rides on a titanium barrel key for long-term durability. This is a rifle for shooters who want signature reduction and serious .50 BMG capability in one package, whether for precision work or demanding field use. An adjustable titanium-and-polymer monopod adds stable rear support for extended strings of fire.
