Rock River Arms worked with some of the industry’s top shooters and manufacturers to create the ideal blend between the action, stock and barrel. The result: RBG-1S, an incredibly accurate rifle that’s customizable and designed for durability and ease-of-use, and it provides great potential for future upgrades. The name breaks down as follows: Rock Bolt Gun, First Generation, Short Action.
At the heart of the Rock River Arms RBG-1S is a purpose-built action from Bighorn Arms, a known quantity in the precision-shooting community. The stainless-steel receiver features an integrated recoil lug, Savage-style small shank thread tenon and an interchangeable floating bolt head. The action features controlled-round feed, as well as a durable fixed ejector and a bayonet-style firing-pin assembly.
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.
