Key Features
- Cold Hammer-Forged Barrel: Why it matters — this process creates a denser, more uniform bore surface, giving you sub-MOA accuracy potential right out of the box. The 18-inch length keeps the rifle handy in brush while still delivering full .22 WMR velocity.
- Power Bedding Integral Bedding Block: Why it matters — the action sits on a rigid, glass-filled nylon bedding block that free-floats the barrel. This eliminates stock-to-barrel contact points that can shift zero, so your point of impact stays consistent shot after shot.
- Interchangeable Comb-Height Modules: Why it matters — whether you're using low-profile iron sights or a high-mounted scope, you can swap the comb insert in seconds for a proper cheek weld. No more awkward chin-on-stock positioning.
- Ruger Marksman Adjustable Trigger: Why it matters — you can dial the pull weight from 3 to 5 pounds without tools. A crisp, clean break helps you shoot tighter groups, especially on small game like rabbits or squirrels.
- Tang Safety with Visible Red Indicator: Why it matters — the safety is right under your thumb and shows a red dot when the rifle is ready to fire. It's intuitive, fast to use, and easy to check even with gloves on.
Who It's For
This rifle is for the hunter who wants a lightweight, accurate rimfire for walking the woods after squirrels or rabbits. It's also a solid choice for the target shooter who appreciates a full-size stock and adjustable trigger. New shooters will find the tang safety and rotary magazine easy to learn on, and experienced shooters will appreciate the threaded barrel for suppressor use. If you want a rimfire that feels like a centerfire rifle, this is it.
Pros and Cons
- Pros: Excellent accuracy for the price; threaded barrel ready for a suppressor; adjustable trigger; two comb heights included; reliable 9-round rotary magazine; American-made.
- Cons: The synthetic stock feels a bit hollow compared to wood or laminate options. Aftermarket stock support is limited compared to 10/22 platform rifles. Also, .22 WMR ammunition costs about twice as much as .22 LR, so factor that into your shooting budget.

Frequently Asked Questions
Can I mount a suppressor on this rifle?
Yes. The barrel is threaded 1/2x28 TPI, which is the standard thread pitch for .22 caliber suppressors. It comes with a thread cap to protect the threads when not in use.
Does the stock have a cheek riser?
It comes with two interchangeable comb-height modules. One is low for iron sights, the other is higher for scope use. You can swap them without tools.
What kind of accuracy can I expect?
With quality .22 WMR ammunition, many shooters report 1-inch groups at 50 yards and 2-inch groups at 100 yards. The cold hammer-forged barrel and Power Bedding system are key to that consistency.
Is this rifle safe for left-handed shooters?
The tang safety is ambidextrous, but the bolt handle is on the right side. Left-handed shooters can still operate it, but it's not a left-eject model.
Does it come with a scope rail?
Yes, the receiver is drilled and tapped for Ruger's scope base pattern. A rail is included in the box, so you can mount rings directly.
