The Primary Weapons Systems Mk111 Mod 1-M upper receiver in 7.62×39 gives you a combat-proven, modular upper built to PWS's exacting standards. Whether you're assembling a new rifle or upgrading an existing one, this 11.85-inch upper combines a short, handy profile with the raw capability of the 7.62×39 cartridge—ideal for intermediate-range shooting, hunting, or tactical applications where compact handling matters. PWS has earned a solid reputation for precision machining and reliability in the field, and this upper reflects that philosophy.
The Mod 1-M designation signals this is PWS's latest iteration of the Mk111 platform. The 11.85-inch barrel length hits a practical sweet spot: short enough to keep overall rifle length and muzzle blast manageable, yet long enough to deliver the velocity and sight radius you need. The FRC (likely referring to PWS's proprietary muzzle or gas system configuration) is engineered to cycle reliably across the wide range of 7.62×39 ammunition types you'll find in the market, from military surplus to modern factory loads.
As an upper receiver assembly, this is the top half of your rifle—you'll need a compatible lower receiver, bolt carrier group, and charging handle to complete the build. PWS uppers are known for tight tolerances and consistent performance, making them a solid choice if you're building a rifle that needs to go to work. The 7.62×39 chambering gives you access to affordable, widely available ammunition while delivering more energy than 5.56 at similar distances.

This is an upper receiver assembly. You'll need a lower receiver, bolt carrier group, charging handle, and magazine to complete a functional rifle.
The compact 11.85-inch length makes this upper well-suited for intermediate-range shooting, hunting, tactical applications, and situations where a short, maneuverable platform is an advantage. The 7.62×39 cartridge delivers solid performance at typical hunting and combat distances.
