RRA Adds Piston-Driven AR-Style Pistol

( -- Rock River Arms new PDS Pistol is the first of a new generation of firearms employing Rock River Arms’ patent-pending Piston Driven System (PDS).

Utilizing a purpose-designed bolt carrier, an adjustable gas piston and an over-the-barrel spring and guide rod arrangement, the Rock River Arms PDS is able to eliminate the traditional recoil system associated with AR-style firearms. The design of the upper receiver and guide rod base prevents gas blow-by to the back of the receiver. The two position adjustable regulator is positioned on the right side of the regulator housing.

Rock River Arms' new PDS Pistol.

The PDS Pistol has a full-length top mounting rail from the rear of the receiver to the regulator housing, allowing flexible placement of numerous optics, lights, lasers and other accessories. The folding ambidextrous, non-reciprocating charging handles may be used independently or in unison to charge the RRA PDS Pistol.

The RRA PDS Pistol features a MS1913 rail on the rear receiver adaptor as well as an MS1913 rail on the regulator housing which allows sling or weapons mounting capabilities. The handguard features an integral Operator Safety Flange to help prevent support-hand movement/slippage towards the muzzle.

Olympic Arms has had these dialed in for awhile now with the OA-93.
Then Sig jumped on board, as no doubt many more companies will in the future.
