Primary Weapons MK118 MOD 2 6mm ARC 18" 15+1 Semi-Auto Rifle

The Primary Weapons MK118 MOD 2 is a semi-automatic rifle chambered in 6mm ARC and built on PWS's signature long-stroke piston operating system. Engineered for long-range performance out of an AR-15-pattern, magazine-fed platform, this rifle pairs an 18" barrel with 15-round capacity, giving shooters a flat-shooting setup well-suited to hunting, target work, and defensive applications at extended distances.

The MK118 MOD 2 uses PWS's long-stroke piston system, engineered for reliable function across a wide range of ammunition and well-suited to suppressed shooting. The rifle features a fully ambidextrous lower receiver with controls mirrored for right- and left-handed shooters, and ships with Magpul furniture. The barrel is finished with PWS's proprietary FRC 2-port muzzle device, and the entire rifle wears a black anodized finish. Manufactured in the USA by Primary Weapons Systems.
