Rock River Arms Announces First Precision Bolt Rifles

Colona, IL – Rock River Arms, one of the industry’s most respected name in Modern Sporting Rifles and pistols, enters the long-range bolt rifle category with the introduction of the all-new RBG Bolt Gun series.

The RBG series bolt rifles are designed to deliver a turn-key precision rifle suitable for long-range shooting and competition. Based on RRA’s proprietary short-action stainless steel receiver and a Wilson (stainless-steel barrel (offered in 24-inch, 22-inch or 20-inch models), the RBG Bolt Gun is available in .308/7.62×51 and 6.5 Creedmoor chambering. The barrel is air-gauged for bore diameter uniformity and cryo-treated to ensure structural consistency.

The barreled action sits in a KRG chassis, which was chosen for its lean profile and precision aluminum bedding. Toolless field adjustability provides a custom fit in any shooting condition. The chassis is compatible with AICS-style detachable box magazines and is ideally suited for multiple long-range shooting disciplines. Color options include tan, black, and green.

Rounding out the action assembly is a one piece, interchangeable two-lug bolt cycled by an oversized knurled bolt handle. The two-lug bolt design provides a smooth action when cycling and features an easy-access external bolt release. Beneath the action is a short-travel Triggertech trigger, or option of a Timney trigger, with adjustable pull weight and a crisp, zero-creep break.

Included with the RBG is a 20 MOA base. This allows the scope to be zeroed to prevent elevation runout for long-distance targets. Standard scope base holes are drilled into the receiver for shooters who desire conventional ring mounts.

Weighing a modest 10.2 pounds with an empty magazine, the RBG Bolt Gun measures 39.5-inches to 43.5-inches in length and is guaranteed by the factory to shoot sub-MOA groups.

    Literally every manufacturer has a sub moa chassis rifle for under $1,200, what makes this worth spending 3x more? Can’t see it.

  2. Jon says:

    That “proprietary” action looks suspiciously like a rebranded Bighorn (which is a good thing)

    • Kyle says:

      It does. Including the barrel nut (which is kinda lame)… So this begs the question, TL3 action, triggertech, KRG chasiss, some steel barrel is worth $4250 how?

  3. roy says:

    I’m seeing at most about $2k of parts and an hour of work for assembly for $4.2K? Am I not seeing this correctly?

    • SSD says:

      I look forward to announcing your highly regulated business manufacturing rifles.

      • Joe says:

        I have a howa 1500 action mounted to an MDT chassis made by legacy sports. Retail for those parts is around $800 and we know legacy didn’t pay retail.

        It reliably shoots half moa and cost $950 out the door.

        Pretty sure Rock River arms is just being stupid here, unless they’re using cardiac surgeons for labor.
