Primary Weapons MK114 MOD 2-M 6mm ARC 14.5" Semi-Auto Rifle

The Primary Weapons Systems MK114 MOD 2-M is a semi-automatic AR-15-pattern rifle chambered in 6mm ARC, built around PWS's proven long-stroke piston operating system for reliable cycling with a wide range of ammunition and in adverse conditions.

The MK114 MOD 2-M features a 14.5" barrel pinned and welded to an FRC 3-port muzzle device, producing a 16" overall length for standard rifle handling in a compact package. The barrel, upper, and lower all wear a corrosion-resistant anodized black finish for a clean, duty-ready appearance.

Chambered in 6mm ARC, the MK114 MOD 2-M delivers impressive long-range ballistic performance from a lightweight, controllable platform. The long-stroke piston system runs cooler and cleaner than direct-impingement designs, making this rifle an excellent choice for duty, defense, and recreational applications alike.
