The billet 7075-T6 receiver set is machined in-house, adding rigidity and strength over standard forged receivers while keeping weight manageable. The Flat Dark Earth Cerakote finish protects the aluminum and blends seamlessly with modern gear.
A short-stroke gas-piston operating system replaces the typical direct-impingement setup. This design vents heat and fouling forward, helping keep the action cleaner and potentially extending maintenance intervals—an advantage in high-volume range sessions or field use.
The 10.5-inch, threaded barrel ends in a three-port muzzle brake that helps tame recoil in the straight-wall .350 Legend cartridge. Combined with the gas-piston system, shooters get a controllable, quick-handling firearm suited to close- to mid-range hunting or defensive roles.
A free-float aluminum M-LOK handguard and full-length Picatinny top rail provide ample space for optics, lights, and other accessories, while keeping the barrel unobstructed for consistent accuracy. A polymer A2-style pistol grip offers a familiar feel for AR shooters.
With a 10+1 capacity and compatibility with widely available .350 Legend straight-wall ammunition, this SAMC-15B is ready for stateside deer seasons, range days, or home-defense duty.
