Primary Weapons Systems Mk114 Mod2-m .338 ARC 16.1" 15-Round Rifle

The Primary Weapons Systems Mk114 Mod2-m .338 ARC 16.1" 15-round rifle is engineered for precision shooters, competitive marksmen, and tactical operators who demand versatility without sacrificing accuracy. This modern intermediate cartridge platform bridges the performance gap between 5.56 NATO and large-format magnum rounds, making it ideal for extended-range applications where terminal performance matters.

Built on Primary Weapons Systems' proven short-stroke piston design, the 16.1-inch barrel optimizes velocity for .338 ARC projectiles while maintaining maneuverability. The rifle features a 15-round magazine capacity, providing adequate firepower for varied mission profiles. The Mod2-m variant incorporates PWS's refined monolithic upper receiver design, which improves structural rigidity and heat dissipation during sustained fire.

At 9.75 pounds fully assembled, this rifle offers a balanced weight distribution that reduces shooter fatigue during long shooting sessions without compromising durability or control. The piston-driven system operates independent of the buffer tube, allowing for enhanced ergonomic stock options and improved reliability across diverse environmental conditions. This rifle is best suited for precision shooting and tactical applications where accuracy and performance are paramount.
