Pws Mk111 Mod Upr 11.85" 7.62x39

The Primary Weapons Systems MK111 Mod Upper 11.85" 7.62x39 is a precision-engineered upper receiver assembly purpose-built for professional operators, competitive shooters, and dedicated rifle builders who demand reliability in intermediate-caliber platforms. Chambered in 7.62x39, this upper represents the evolution of PWS's proven modular design philosophy, combining modern ergonomics with the ballistic efficiency of a cartridge trusted by military and law enforcement worldwide.

Designed for shooters who refuse to compromise between accuracy and dependability, the MK111 Mod fills a critical niche for those running AK-pattern or AR-pattern hybrid systems. Featuring an 11.85-inch barrel, this upper delivers optimal velocity and handling characteristics for close-to-mid-range tactical applications and three-gun competition, balancing muzzle velocity against maneuverability in confined spaces. The modular design incorporates Primary Weapons Systems' refined upper receiver platform, engineered for minimal tolerance stack and maximum durability under sustained fire.

At 4.25 lbs, the MK111 Mod upper maintains a lightweight profile ideal for operators conducting extended patrols or tactical movements where cumulative weight directly impacts mission performance. The precision-machined receiver surfaces ensure consistent bolt carrier cycling and repeatable accuracy, while the 7.62x39 chamber supports both standard and boutique ammunition loads. Law enforcement tactical teams and military personnel will find this upper to be an invaluable addition to their arsenal.
