Colona, IL –-( Rock River Arms has the reputation for producing top quality AR15s.

What sets Rock River Arms apart from the competition is their versatility to produce and innovate weapons to such rigorous specifications.

The Rock River Arms 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 completely eliminate the traditional recoil system associated with AR-style firearms, making for an extremely versatile weapon platform. 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 conveniently positioned on the right side of the regulator housing.

The New 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.

I purchased the PDS, changed out the fore-grip for a quad-rail and paid the $200 to add RRA’s folding stock. Shoots like a DREAM. Only downside (like most SBRs) LOUD as crap. Piston is much cleaner than gas.

I love it!

I'm interested in the RRA PDS pistol….How much??? Do you have a catalog ??? I'm not familiar with .223 Cal. what is that equal to ???

I am a retired Illinois State Trooper and familiar with the Rock River area…I think that PDS pistol would be really great to carry in the car…I also have a LEOSA permit …
