Rock River Arms has announced the commercial availability of their first precision bolt gun: the RBG-1S. After the original RBG bolt gun was announced back in 2019, the RBG-1S marks Rock River’s first effort in the precision rifle market.

RRA has been building AR-pattern rifles for years. They offer other firearms as well, including a polymer 1911. So how did they approach their precision bolt gun build?

The story of the RBG-1S [Rock/River Bolt Gun, 1st Generation, Short-action] begins with a Bighorn Arms action. That action, a TL3, is seated in a Kinetic Research Group chassis. Also nestling in that KRG Whiskey-3 chassis is an RRA-finished Wilson barrel. Below that our story may vary, from either a Triggertech or Timney trigger.


The rifle feeds from AICS style mags and will be initially available in .308 and 6.5 Creedmoor.

Rock River Arms says the RBG-1S is . . .

…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 .308/7.62x51and 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 the 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.

  1. Did Rock River Arms support/side with Democrats and civilian disarmament in their home state of Illinois?

    If they did, I would be inclined to purchase their firearms because … ??????

        • The motto of Clan Campbell (the most ruthless and feared of the Highland Clans; I’m 1/4 Campbell) is “Ne Obliviscaris” (literally, “forget not,” but contextually meaning “don’t forget or forgive an injury/insult”).

          Applies perfectly to Springfield Armory and Rock River Arms.

          They sold us out, and then tried to lie their way out of it.

          Don’t forgive. Don’t forget. Don’t give them a dime.

    • Rock river arms along with springfield armory are responsible for the closing of countless small local Illinois guns shops (including my fav). These traitors will never see another nickel from me.

    • Because they are so inexpensive, such a great value! Of course, they’l need to drop at least $3000 from that price for that to be a reason, but hey …

  2. Are precision rifles the new AR15? As in how everybody and even their grandmothers dead cat came out with their own line of ARs back in 2012ish to 2017. I could see hordes of people lining up for a cheap($$) semi auto that’s constantly shilled by the brady bunch and co. but $2k or more for bolt guns that still require you to drop bills on a good piece of glass.

    • There are two simple explanations in this case. Rock River Arms, who supports Democrats and civilian disarmament:

      1) Is hedging their bets so that they can still sell something if Democrats achieve their dream of making possession/ownership of military-style rifles illegal.

      2) Like their Far Left compatriots comrades, knows better than everyone else (how dare you question their business strategy of selling rifles with ridiculous price tags!) and is certain that people will line up in droves to purchase their rifle.

      • I disagree with your premise. Guns are like bicycles, or vehicles, golf clubs, liquor, or anything else in demand.

        After years of gun writers and “experts” admonishing anyone who didn’t get in close for the shot, now it seems everyone needs a rifle that will shoot beyond the old 400 yd max. Of course, it won’t be something you’ll be able to take into the “field”- you’ll need a good bench w/bags plus a range with more than the normal 200 yd distance to even get anything out of the precision rifle that you can’t do with your Model 70.

        Me? Have to admit I’m looking at precision rifles after shooting the 1 mile course a couple years back at the Whittington donor’s weekend. It’s pretty cool to shoot 3 of 5 shots into a roughly 1 foot triangle from a mile distance but I’m also smart enough to realize that it was the spotters from Hill Country Rifles, who built the rifle, who coached me. And I’m not interested in some 6.5 Creedmoor or .30 PRC- if I’m going to do it I’ll go for minimum of .338 Lapua.

        Basically, it’s all about toys and bragging rights. Just like everything else in firearms marketing.

        • “..minimum of .338 Lapua..”

          Even in normal times that’s an expensive date to feed.

          But yeah, if you’re going to, that’s the way to go.

        • *Minimum* of .338 Lapua? What is higher up the scale, the Warthog’s 30 mm? I know that’s good for 4-5 miles. Not sure about the moa, tho. I don’t think it’s gonna fit in your Ferrari, either.

        • “*Minimum* of .338 Lapua? What is higher up the scale, the Warthog’s 30 mm?” Well, .375 Chetac, .416 Barrett or the obvious, and th one with the most available “factory ammo”, the .50 BMG. I’ve shot a number of .50s, just think I’d probably use it less than a .338 Lapua.

    • I think there are two basic things going on.

      1) Long range competitions and long range tactical classes have gained in popularity.

      2) There seems, at least I sense, a bit of a return to rifle fundamentals, which allow for and encourage longer range shooting.

      You eventually hit the point with carbines and pistols that it either gets boring or upping your game requires enough time and money investment that it’s not worth it. Rather than going through thousands of dollars in upgrades for marginal gains in a set of skills they’re unlikely to ever use people put that disposable income into acquiring another shooting skill because it’s the same money and more enjoyable. Sometimes it’s trap and skeet, sometimes it’s wheel guns. Sometimes it’s reaching out 800+ yards with consistency.

      And then there’s the “Ooooooo…. what’s this over here?” factor.

      • > Sometimes it’s reaching out 800+ yards with consistency.

        And after semi’s, the left will come for their freshly renamed “sniper rifles.”

        There’s no end to what they want. Vanquished the boogieman? Create a new one.

  3. RBG 1-S ? Finally, a rifle named for Ruth Bader What’sHerName. Man, I’m all in for that.


  4. so they buy the action, the trigger, the stock and the magazine from someone else….

    how exactly are they manufacturing it?

  5. Fuck Rock River Arms and their support of anti gun legislation. Fuck Springfield too. Unless and until they replace senior management no Second Amendment supporter should purchase their products.

  6. I have an RRA .308 that was left to me. It’s a fantastic rifle, but I would never spend the dough based on their past. I’ve never seen an apology from them for any of their actions. Unacceptable. I love this rifle, but would never spend a single dollar to purchase another one of their new guns.

    • I know where they’re coming from. I bought the bride a S&W Airweight less than a week before the company sold out 2A, nice gun, no problem keeping it (although it hurts like hell to shoot it with plus-P), but would never buy another until the owners lost their damn shirts due to a totally unmentioned boycott for many years, they finally bailed. So now all is forgiven, but at the time it was traumatic. How dare they!?

  7. If one were to get “serious” about PRS competitions, and have the means, by all means.

    I got a old FNH Patrol Bolt Rifle (take a Winchester Model 70, put on a medium contour 24inch barrel, Hogue stock) that shoots MOA with match ammo/handloads all day.
    $800 out the door.
    With some handloads, VDL bullets, I probably could make the 1,000yrds mark.
    But around here, taking a shot past 400yrds is next to nil.

  8. “RRA has been building AR-pattern rifles [and suppressing Illinoisians’ gun rights] for years.”
