Overall Length – 20.6″

Barrel Length – 11.85″

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.

Position 1 is normal operation with standard and some military ammunition.

Position 2 is for suppressor use when running standard ammumition.

Position 3 is for suppressor use with hotter loads such as military ammumition.


Smooth Recoil Impulse

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