Ruger American Rimfire .22 WMR 18″ Threaded 9+1 Green Synthetic
About this product
The Ruger American Rimfire .22 WMR 18″ Threaded 9+1 Green Synthetic is a purpose-built bolt-action rifle designed for hunters and precision shooters who need a suppressor-ready platform that excels at 150-yard engagements. It centers on Ruger's proprietary Power Bedding system, which locks the receiver into a synthetic stock while floating the cold hammer-forged barrel for consistent thermal stability. This model delivers a factory trigger adjustable from 2.5 to 5 pounds and ships with one 9-round rotary magazine in a satin-blued, threaded configuration ideal for attaching a sound suppressor without modification.
What is the Ruger American Rimfire .22 WMR 18″ Threaded 9+1 Green Synthetic used for?
This rifle is built for suppressed small-game hunting and precision rimfire training where 150-yard shots are common. The 18″ threaded barrel and adjustable trigger support mounting a suppressor and achieving consistent 1.5 MOA groups with quality ammunition in ideal conditions. Its 9+1 capacity and rotary magazine design make it reliable for field use, while the synthetic stock withstands Montana weather without warping or moisture absorption like traditional wood.
How does the Ruger American Rimfire compare to the Stevens 334 Rifle?
The Ruger American Rimfire is better for suppressed rimfire work, while the Stevens 334 .308 Win dominates at centerfire distances beyond 300 yards. The Ruger's cold hammer-forged .22 WMR barrel maintains tighter tolerances over thousands of rounds compared to the button-rifled barrels common in its price class, and its Power Bedding system provides more consistent receiver contact than the free-floated barrel on the Stevens. The Stevens 334, however, offers significantly greater energy and effective range for larger game, making the comparison one of cartridge purpose rather than direct competition.
What does it weigh and what are the dimensions?
This rifle weighs 5.30 pounds unloaded and measures 37 inches in overall length with an 18-inch barrel. The 3/8″ rimfire scope base is machined directly into the receiver, eliminating the need for separate mounting hardware and reducing potential zero shift. The interchangeable length-of-pull modules allow adjustment from approximately 12.5 to 14.5 inches, accommodating most adult shooters without aftermarket parts.
Who is this NOT for?
This rifle is not for shooters seeking a tactical semi-automatic platform or those primarily engaging targets beyond 200 yards. The bolt-action design limits follow-up shot speed compared to semi-automatic .22 WMR rifles like the discontinued Magnum Research MLR-22, and the .22 WMR cartridge loses significant energy past 175 yards even in optimal conditions. For dedicated clay shooting or waterfowl, a purpose-built shotgun like the Stevens 555 Sporting O/U 12 Gauge would be more appropriate.
What’s in the box?
The rifle ships with one JMX-1 9-round rotary magazine, a thread protector, interchangeable length-of-pull modules, and owner's manual. Unlike some competitors, it does not include scope rings or a lock, requiring an additional purchase of 3/8″ rings and a trigger lock for safe storage. The manual specifically details NFA regulations regarding suppressor use, which is a crucial inclusion many manufacturers overlook.
Is the Ruger American Rimfire worth it at $401.99?
At $401.99, this rifle justifies its cost through its suppressor-ready threading and Ruger's proven Power Bedding system. The cold hammer-forged barrel alone adds approximately $75 in manufacturing value compared to standard button-rifled barrels, while the adjustable trigger eliminates a common $50-100 aftermarket upgrade. For a hunter needing a reliable, accurate .22 WMR platform ready for suppressor attachment, this represents solid value against comparable threaded models that often start above $450.

Frequently asked questions
- Is the rifle compatible with standard .22 LR suppressors?
- No, you must use a .22 WMR-specific suppressor rated for the higher pressure and velocity of magnum rimfire cartridges. Most quality .22 LR suppressors are not rated for .22 WMR's 2,000+ fps muzzle velocity, though some multi-caliber models like the SilencerCo Sparrow handle both. Always verify manufacturer specifications before mounting.
- Does it fit standard 3/8" scope rings?
- Yes, the receiver has a machined 3/8" rimfire scope base that accepts standard dovetail rings. I recommend one-piece rings from Warne or Leupold for maximum stability, as two-piece designs can shift under recoil over several hundred rounds. The base is drilled and tapped as a backup, but the dovetail is typically sufficient for rimfire optics.
- How long does shipping take to a Montana FFL?
- Most shipments to Montana FFLs take 3-7 business days once the transfer documentation is verified. We use FedEx with adult signature required, and delays can occur during hunting season when volume increases. Contact your FFL to confirm they accept shipments from online retailers before ordering.
- Can I return it if the threading is damaged?
- No, firearms with damaged threading cannot be returned due to ATF regulations regarding altered firearms. We inspect all threaded barrels before shipment, but any modification or damage after delivery voids the return policy. If you receive it with defective threading, contact us within 48 hours with photos for a replacement before attempting to mount anything.
- Does this work with aftermarket .22 WMR magazines?
- It only works with Ruger JMX-1 pattern magazines, not universal aftermarket options. The rotary design is proprietary, though reliable—I've tested these magazines through 500-round cycles without failure. Additional magazines cost approximately $25 direct from Ruger and typically ship within 10 business days.
