$497.19
Ruger’s 8351 American Rimfire Full Size 22 LR delivers sub-MOA accuracy with its Power Bedding system, cold hammer-forged threaded barrel, and adjustable Marksman trigger—all for under $450. Suppressor-ready and 10/22-mag compatible.
The Ruger 8351 American Rimfire Full Size 22 LR is a precision .22 LR bolt-action built on Ruger’s patent-pending Power Bedding system—an integral bedding block that locks the receiver in place and free-floats the cold hammer-forged barrel. This satin stainless steel threaded barrel model with scope rail and black synthetic stock delivers sub-MOA accuracy straight from the box, in a right-hand configuration that serious rimfire shooters can trust at the range or in the field.

Key Features
- Power Bedding Integral Bedding Block – Why it matters: This patent-pending system positively locates the receiver and free-floats the barrel, eliminating bedding inconsistencies that degrade accuracy. You get repeatable sub-MOA groups shot after shot.
- Cold Hammer-Forged Barrel – Why it matters: The ultra-precise rifling from the hammer-forging process delivers exceptional accuracy and longevity, plus it’s easier to clean than cut-rifled barrels. Expect consistent performance even after thousands of rounds.
- Ruger Marksman Adjustable Trigger – Why it matters: The trigger pull is user-adjustable from 2.25 to 5.0 pounds, letting you dial in a crisp break for precision shooting. No aftermarket trigger needed.
- Threaded Barrel (1/2×28 TPI) – Why it matters: The 18-inch threaded barrel allows direct mounting of a suppressor or muzzle device without adapters, making it suppressor-ready out of the box.
- Integrated 3/8″ Rimfire Scope Base – Why it matters: The receiver is machined with a 3/8″ dovetail and also drilled and tapped for scope mounts, giving you flexibility to run rings or a rail. Included Williams fire sights offer a backup.
Who It’s For
This rifle is built for the precision rimfire shooter who wants a factory-accurate .22 LR for target shooting, small-game hunting, or training. It’s also ideal for shooters transitioning from a 10/22 to a bolt-action platform who want the same magazine compatibility and reliability.
Pros / Cons
- Pros: Sub-MOA accuracy out of the box; suppressor-ready threaded barrel; adjustable trigger; accepts 10/22 magazines; Power Bedding system free-floats barrel; satin stainless finish resists corrosion.
- Cons: The synthetic stock is functional but lacks the adjustability of a chassis system; the action can feel a bit stiff until broken in (common with new Ruger rimfires).

FAQ
Does the Ruger 8351 come with a scope rail?
Yes—this model includes an integrated 3/8″ rimfire scope base machined into the receiver, plus it’s drilled and tapped for additional mounting options. A scope rail is not included, but the base is ready for rings or a separate rail.
What suppressor mounts work with the threaded barrel?
The barrel is threaded 1/2×28 TPI, which is the standard for .22 LR suppressors. Most rimfire cans like the SilencerCo Sparrow, Dead Air Mask, or Ruger Silent-SR will thread directly on without an adapter.
Is this rifle compatible with 10/22 magazines?
Yes—the American Rimfire uses the same 10/22-style rotary magazines, so you can use your existing 10/22 mags. It ships with one 10-round magazine.
How do I adjust the trigger?
The Ruger Marksman trigger is user-adjustable via a small hex screw inside the trigger housing. You can set pull weight from 2.25 to 5.0 pounds. Refer to the manual for exact steps.
What’s the accuracy potential of this rifle?
With quality match ammo, expect consistent sub-1 MOA groups at 50 yards. The Power Bedding system and free-floated barrel are key to this performance. Many shooters report 0.5–0.75 MOA with premium loads.
Bottom line: The Ruger 8351 American Rimfire Full Size 22 LR is a factory-accurate, suppressor-ready bolt-action that punches above its price point. With a proven bedding system, adjustable trigger, and 10/22 magazine compatibility, it’s a smart buy for any precision rimfire shooter.
