The PWS Long Stroke Piston


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.

Adjustable Gas Block

Our three 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 resulting in a quieter operation.


Smooth Recoil Impulse

A detachable floating piston head is attached directly to the operating rod which 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.
