The Primary Weapons Systems MK2 MOD2 .308 Semi-Auto Rifle (brand part no. MK2M2R30816) pairs a 16-inch barrel with PWS’s proven long-stroke gas piston system, chambered in the hard-hitting .308/7.62 NATO cartridge. PWS has earned a strong reputation among competitive and duty shooters for the fit, finish, and reliability of its piston-driven AR-pattern rifles, which run cooler and cleaner than direct-impingement designs. The MK2 MOD2 platform brings that engineering to a big-bore semi-auto rifle, and a 20-round magazine ships ready to run. It is built for shooters who want a serious .308-caliber AR-10-pattern rifle without compromising on reliability.
