The Rock River Arms PDS – Piston Driven System – may not be new, but this SBR certainly is. At the Rock River Arms booth at SHOT Show this year they showcased a few guns so new they had little information available beyond the caliber and length of barrel. This particular rifle is an SBR with a 9″ barrel. It’s chambered in 5.56 NATO and was fun just to hold, so it should be even better to shoot.
