Product Description

Fitted with a 7.75 inch barrel, which is the shortest available, Omaha Outdoors carries the PWS MK107 MOD 1 upper receiver for your next custom pistol build. It features the Primary Weapons Systems long stroke piston operating system, which is much cleaner than gas impingement. That means fast cleaning after a shooting session. It's chambered in 223 Wylde, so there's no issue with overpressure. The PWS MK107 MOD 1-M upper features include a forged and anodized proprietary piston upper, a 3-position gas regulator, a Triad muzzle device, and a Radian Raptor Ambidextrous charging handle. With a PWS MK107 MOD 1 7.75-inch upper, you can build a custom AR pattern pistol with your choice of lower receiver. Omaha Outdoors has the PWS MK107 MOD 1 upper for sale, so go online and check for availability.
