Rock River leans on Wilson Arms for supplying a high-quality barrel blank that RRA stress relieves and cryogenically treats that is known to produce a high level of accuracy. To provide the user interface RRA partnered with Kinetic Research Group (KRG) for its Whiskey-3 chassis. Shooters will have the ability to fine tune the rifle to their needs depending on shooting style. KRG supplies a straight pistol grip and a customizable fore-end with accommodation for M-LOK, Picatinny rail, and ARCA-style rail for use with bipods and other accessories.
