PWS MK2 MOD2 .308/7.62 NATO 16.1-inch AR Rifle

The PWS MK2 MOD2 (brand part number MK2M2R30816) is a semi-automatic AR-pattern rifle chambered in .308/7.62 NATO from PWS, built around the company’s long-stroke gas piston system for a cleaner, cooler-running action than a standard direct-impingement AR-10. It’s designed for shooters who want battle-rifle power in a modern AR platform for hunting, home defense, or duty-grade range work.

Key Specifications

• Chambered in .308 Winchester/7.62 NATO, a hard-hitting cartridge trusted for hunting and duty use.
• The 16.1-inch barrel keeps the rifle maneuverable while staying within standard-length AR-10 configuration.
• A 20-round magazine gives the MK2 MOD2 serious standard-issue capacity.
• Its MK216 model long-stroke piston action runs cleaner and cooler than direct-impingement AR-10 designs.
• The semi-automatic action allows fast, controlled follow-up shots on target.
• As an AR-pattern rifle, it retains the familiar controls, ergonomics, and accessory compatibility of the AR platform.
• It’s classified as an AR-type rifle, built for two-handed, shoulder-fired use.
• The long-stroke piston action moves the bolt carrier group’s operating rod separately from the gas system, reducing carrier tilt compared to direct impingement.
• PWS builds the MK2 series specifically around .308-class AR platforms rather than adapting a 5.56 upper.
