Built for shooters who demand performance at distance, this upper features an 18-inch mid-weight barrel with a fast 1:7.5 twist rate and a 5\/8-24 threaded muzzle, making it suppressor-ready right out of the box. Powered by PWS's proven long-stroke piston operating system paired with a three-position adjustable gas block, the MK118 MOD 2-M delivers exceptional reliability and significantly reduced carbon fouling compared to direct impingement designs. The PicLok handguard offers both Picatinny rail sections and M-LOK attachment points for maximum accessory compatibility, while the Radian Raptor ambidextrous charging handle ensures smooth operation for all users. The upper is finished in a durable black-anodized aluminum construction and fits standard mil-spec AR-15 lower receivers.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6mm ARC Chambering:\u003c\/strong\u003e Optimized for long-range precision, the 6mm ARC cartridge delivers flat trajectories and impressive ballistic performance from an AR-15 platform.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18-Inch Mid-Weight Barrel:\u003c\/strong\u003e 1:7.5 twist rifling and a 5\/8-24 threaded muzzle provide outstanding accuracy and seamless suppressor compatibility.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong-Stroke Piston System:\u003c\/strong\u003e Three-position adjustable gas block ensures reliable cycling in all conditions while dramatically reducing heat and carbon buildup in the receiver.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePicLok Handguard:\u003c\/strong\u003e Dual-compatible Picatinny and M-LOK handguard allows versatile mounting of lights, grips, lasers, and other accessories.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadian Raptor Ambidextrous Charging Handle:\u003c\/strong\u003e Premium charging handle included for effortless, ambidextrous operation straight from the factory.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Primary Weapons Systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e MK118 MOD 2-M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number (MPN):\u003c\/strong\u003e MK1M2U6ARC18NC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 811154033284\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber\/Gauge:\u003c\/strong\u003e 6mm ARC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Twist Rate:\u003c\/strong\u003e 1:7.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threading:\u003c\/strong\u003e 5\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Profile:\u003c\/strong\u003e Mid Weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Fluting:\u003c\/strong\u003e None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Long-Stroke Piston\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block:\u003c\/strong\u003e Three-Position Adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandguard:\u003c\/strong\u003e PicLok (Picatinny and M-LOK Compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharging Handle:\u003c\/strong\u003e Radian Raptor Ambidextrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFirearm Fit:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Anodized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreaded Barrel:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuppressor Compatible:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 5.65 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
