POTLATCH, ID –-( PNW Arms releases Signature Series Designated Marksman Rifle (SSDMR) in .300 Blackout, in partnership with their commercial distributor Snake River Shooting Products & Consulting Inc (SRSP).

Featured in Guns & Ammo Book of the AR-15 this month as the cover story, this rifle is truly state of the art in performance, accuracy, and design.  PNW has kitted the rifle out utilizing the most cutting edge tech available in the black rifle market today, and has built out a beautiful package for the shooter.  PNW is routing the rifles exclusively via their commercial distributor, SRSP.
