The 6mm ARC cartridge changed the conversation about what an AR-15 sized rifle can do at distance, and the PWS MK114 MOD 2-M is one of the better platforms to run it in. Primary Weapons Systems builds this rifle around their long stroke piston system, the same AK-inspired operating method they have refined for years. The result is a gun that stays cleaner in the receiver, runs cooler, and cycles smoothly whether you are shooting bare muzzle or hanging a can off the front. The 3-position adjustable gas block lets you dial things in for suppressed or unsuppressed shooting without tools or fuss.
The 14.5 inch barrel is made in Boise with a 1:7.5 twist that stabilizes the full range of 6mm ARC loads, from light varmint bullets to heavy match projectiles. PWS backs every rifle with a sub-MOA accuracy guarantee when fed quality ammo, which is real confidence from a factory gun. The FRC 3-port compensator is pinned and welded to bring overall length to 16.1 inches, and it does double duty by taming recoil and muzzle rise while playing nice with the Rearden Atlas suppressor mounting system.
The receivers are machined from 7075-T651 forged aluminum, and the in-house lower design is fully ambidextrous with a flared magwell and integrated trigger guard. PWS skipped the forward assist to keep the upper trim and rigid. The PicLok handguard blends Picatinny and MLOK mounting into one system, a Radian Raptor ambidextrous charging handle handles the controls, and the enhanced buffer system with its H2 steel buffer smooths out an already soft-recoiling cartridge. Magpul MOE SL stock and MOE K2 grip round out the furniture.
At 6.9 pounds unloaded, this rifle carries easily in the field but settles down nicely on a bag or bipod. It is a strong pick for coyotes and deer-sized game at extended range, steel work past 600 yards, or anyone who wants gas gun reliability with bolt gun manners. Every PWS firearm is covered by their transferable lifetime warranty.
Yes, this is one of its strong suits. The long stroke piston system keeps gas out of the receiver and away from your face, and the 3-position adjustable gas block lets you tune the rifle specifically for a suppressor. The FRC 3-port compensator is also compatible with the Rearden Atlas mounting system, so adding a can is straightforward.
PWS guarantees sub-MOA performance with quality match-grade ammunition, sound fundamentals, and a stable position. The Boise-made barrel has a 1:7.5 twist that handles everything from lighter loads to heavy 105+ grain match bullets, and 6mm ARC itself was designed to stay supersonic well past 1,000 yards.
A long stroke piston vents gas at the block instead of dumping it into the receiver, so the action stays cleaner and cooler even after high round counts. That means less scraping carbon off your bolt carrier and more consistent cycling, especially when running suppressed. It is the same basic operating principle that made the AK famous for reliability, applied to the AR platform.
Absolutely. The 6mm ARC shoots flat with mild recoil and retains energy well at distance, making it a solid choice for deer-sized game, hogs, and predators. At 6.9 pounds unloaded, the rifle is light enough to carry all day without wearing you out.
