Product Description

The PWS MK107 Pistol was developed for those who desire the MK107 rifle, but cannot possess a short-barreled rifle. The short, compact design retains lethal capability out to 200 meters and has been proven highly effective with very little sacrifice over a standard rifle.

As the only piston-driven pistol on the market today that was designed from the ground up as a 7 platform, the PWS MK107 pistol is a dream come true for those looking for the shortest possible package and the reliability of a full-size rifle. The operating system, designed after the venerable AK-47, features a long-stroke fixed operating rod design with an adjustable gas block, 7 handguard and free-floated barrel.

The handguard features the VLTOR KeyMod System which comes standard with two 2 sections of 1913 rail as well as a continuous 1913 top rail.

Understanding the importance of an ultra-reliable package that is light as possible, mil-spec forgings are used for the upper and lower receiver. Additional features include the BCM GUNFIGHTER charging handle, the PWS Enhanced Buffer Tube and an ALG Defense QMS trigger. The pistol is rounded out with industry-leading features such as Magpul MOE grip, and MBUS2 sights.
