Colona, IL --(Ammoland.com)- 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.

Nice! A piston powered pistol. No buffer tube sticking out the back.

That new Ruger clone AR is a piston job right?

[3boysdad]

I never plan on letting them get that close.

[smokingfrog]

Yea. The Ruger has a piston.

Almost everyone makes a piston AR now.

But it’s great for drive-byze with yer homies.

Pulling this trigger takes 2.
I'm lazy.

Now that’s an interesting design.

Guess you gotta use a smaller mag and hollow points to get the weight down. 5 lbs for a “pistol” is a bit much.

Only about 6 years behind the times:

The Kel Tec PLR-16, a piston-driven, AR-style, 223 caliber pistol that takes standard AR magazines:

Typical "street" price is around $450, and it's just over 3 pounds - pretty light and low cost!

[MHGinTN]

It's more like a 'machine pistol' ... think KelTec SR16 (?) but at $1300!

[MHGinTN]

Beat me by thiiiiiis much. LOL

[smokingfrog]

Definitely cheaper than the RR, but the sights look kind of cheezy. Of course, you could afford to buy an Aimpoint with the price difference.

[PugetSoundSoldier]

Heheh... But you posted the most important differentiation:

$1300 for the RRA PDS

That's crazy expensive! You could get a PLR-16, AND a dozen, fully loaded PMAGS, AND still have enough left over to buy a Glock G17!

[Tainan]

IMO these are not ‘pistols’...they are CQB SMGs.(non-auto in civilian versions)

Just my opinion...not saying they don’t have a place.

[MHGinTN]

I’m saving for the ‘30’ in .22 mag.

[PugetSoundSoldier]

Of course, you don’t even GET sights with the RR...;) Yeah, for the difference, an Aimpoint, or a Magpul BUS set mount. And the extra $700 buys a LOT of ammunition or reloading supplies.

[MHGinTN]

I have one of the KelTec 9mm folding carbines. Right out of the box it shot four inch groups at ten yards. And I bought the Glock mag version so I could use 33 round mags with it. Thing folds up and carries in a book bag!
