The PWS MK107 (Diablo) Rifle was developed specifically for CQB requirements and as a replacement option for MP5-style weapons. The short compact design retains lethal capability out to 200 meters and has been proven highly effective in the military and law enforcement community.

The PWS long-stroke piston system combines the agility of the AR-15 with the reliability of the AK-47 into a sleek and efficient design. Our four position adjustable gas block restricts gasses, rather than venting them from the side. This allows the unused gas to exit from the front of the gun, rather than the sides of the gas block, resulting in a more quiet operation.

A floating piston head, detachable for charging handle replacement, is attached directly to the operating rod, which in turn is securely attached to the carrier. With only one moving assembly, the PWS long-stroke piston system offers a lighter recoil impulse, while at the same time providing increased longevity and durability.
