The RRA PPS Carbine is one of a new generation of
firearms employing RRA’s patent-pending Performance
Piston System (PPS). Featuring a purpose-designed bolt
carrier, an adjustable gas piston and an over-the-barrel
spring and guide rod arrangement, the RRA Performance
Piston System is able to completely do away with the traditional
recoil system associated with AR-style firearms,
making for an extremely versatile weapon platform.
Several exciting new models are scheduled for release in
2010, as well as specialized parts and accessories.
