Primary Weapons Systems MK116 MOD 2-M .223 Wylde - AR-15 Rifle - 1x 30rd Mag

When you demand piston-driven reliability, sub-MOA accuracy, and suppressor-ready performance in a lightweight .223 Wylde AR-15, the Primary Weapons Systems MK116 MOD 2-M delivers all three — and includes a 30-round magazine ready to run.

The Primary Weapons Systems MK116 MOD 2-M is an AR-15 rifle designed for shooters who require precision-grade accuracy, reduced fouling, and seamless suppressor integration in a sub-7-pound package.

At the core of the MK116 MOD 2-M is the PWS Long Stroke Piston System — an operating system renowned for cycling reliability, reduced carbon fouling in the receiver, and cooler, cleaner operation over sustained fire. The three-setting Adjustable Gas System lets you dial in optimal gas flow for a wide range of ammunition types and suppressor configurations, minimizing blowback and back pressure when suppressed. PWS backs their Boise-made precision barrels with a sub-MOA accuracy guarantee using high-grade ammunition, and the 16.1" .223 Wylde barrel with a 1:8 twist rate accommodates both .223 Remington and 5.56mm NATO with equal reliability. The PicLok handguard integrates both Picatinny and M-LOK attachment zones in a single system, and the Radian Raptor ambidextrous charging handle and ambidextrous lower receiver ensure smooth operation for both right- and left-handed shooters.

Chambered in .223 Wylde, compatible with both .223 Remington and 5.56mm NATO. The ambidextrous lower receiver features a flared mag well and built-in trigger guard. Compatible with the Rearden Atlas suppressor mounting system via the FRC 2-Port Compensator. Comes equipped with Magpul MOE SL stock and MOE K2 pistol grip. Includes 1x 30-round magazine.

The 7075-T651 forged aluminum receiver is anodized for durability. The Enhanced H2 Steel Body Buffer with 1.2" diameter enhanced buffer tube and ratchet lock with built-in QD mount provides effective recoil management. The PTFE-coated mil-spec enhanced trigger breaks at 5.5 to 6.5 lbs for a crisp, consistent pull. Complete rifle weight is just 6.8 lbs unloaded.

Purpose-built for precision shooting, suppressed use, competition, and demanding range applications. The long-stroke piston system and adjustable gas settings make the MK116 MOD 2-M particularly well-suited for running suppressed across a wide variety of ammunition.
