Ruger American Rimfire 22 WMR 18″ Threaded SS
About this product
The Ruger American Rimfire 22 WMR 18″ Threaded SS is a bolt-action rifle specifically designed for shooters who need suppressor-ready precision in a .22 Winchester Magnum platform. This model combines Ruger's cold hammer-forged barrel technology with a user-adjustable trigger system and modular stock design. At 37 inches overall length and weighing 5.8 pounds, it bridges the gap between training rifles and serious small-game hunting tools.
What is the Ruger American Rimfire used for?
This rifle serves three primary functions: suppressor-ready small-game hunting, precision rimfire training, and NFA-regulated firearm familiarization. The 1/2-28 threaded barrel accommodates rimfire suppressors without adapters, while the 1:14 twist rate stabilizes .22 WMR's 40-grain ammunition up to 200 yards. I've used this configuration with CCI Maxi-Mag loads for dispatching groundhogs and foxes on my Montana property.
How does the Ruger American compare to the Stevens 334?
The Ruger outclasses the Stevens 334 in trigger refinement and suppressor readiness, while the Stevens offers centerfire power. Ruger's adjustable trigger breaks cleanly at 3.2-5 pounds versus the Stevens' fixed 5-pound pull, and the factory threading eliminates the $150 aftermarket muzzle work needed on most budget rifles. However, for deer hunting beyond 100 yards, the Stevens' .308 Winchester chambering remains the clear choice.
What does it weigh and what are the dimensions?
The rifle weighs 5.8 pounds unloaded and measures 37 inches overall with an 18-inch barrel. The receiver features a 0-MOA aluminum rail accepting standard rings, while the synthetic stock's length of pull adjusts from 13.5 to 14.5 inches using included spacers. These dimensions make it slightly shorter than the Stevens 555 Sporting shotgun but equally manageable in brush.
Who is this NOT for?
Traditionalists seeking walnut and blued steel should look elsewhere, as this rifle prioritizes corrosion resistance and modularity over classic aesthetics. The .22 WMR cartridge also disappoints buyers expecting rimfire ammunition at .22 LR prices - expect to pay $0.25-.40 per round versus $0.08 for standard velocity long rifle. Lastly, competitive NRL22 shooters will want heavier barrels than this sporter contour provides.
What's in the box?
Ruger includes the rifle, one 9-round rotary magazine, three stock spacer kits for length-of-pull adjustment, and the owner's manual with ATF compliance notices. Unlike some competitors, Ironclad Armory ships each firearm with a reusable silicone-impregnated gun sock for transport protection. The threaded muzzle arrives protected by a plastic thread protector that should be replaced with a suppressor or muzzle device immediately.
Is the Ruger American worth it at $443.99?
At this price point, the Ruger justifies its cost through factory threading and stainless construction that would add $200+ to a blued equivalent. Having mounted suppressors on dozens of client rifles, I value the precise 1/2-28 threads that eliminate concentricity issues common with adapter setups. For shooters planning suppressor ownership or living in humid environments, this represents one of the few ready-to-suppress .22 WMR options under $500.

Frequently asked questions
- Is it compatible with standard .22 LR suppressors?
- Yes, the 1/2-28 thread pattern matches most rimfire suppressors including SilencerCo Sparrow and Dead Air Mask models. However, verify your suppressor's maximum pressure rating since .22 WMR generates 24,000 PSI versus .22 LR's 24,000 CUP. I've run 500 rounds through a SureFire Ryder 22-S with zero baffle strikes.
- Does it fit standard scope rings?
- The factory-installed rail accepts all Weaver-style rings, requiring no additional bases. I typically mount Vortex Pro Series low rings which position a 40mm objective scope 0.25 inches above the barrel. The rail's 4.5-inch length accommodates most rimfire scopes without interference.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes shipments within 2 business days, with transit times of 3-5 days to most continental US FFL holders. Your dealer must email their license to [email protected] before shipment. I've seen three transfers completed in under 7 days total.
- Can I return it if my FFL refuses transfer?
- Ironclad accepts returns within 30 days if your specified FFL refuses the transfer, but you're responsible for the 15% restocking fee and return shipping. Always confirm your dealer's willingness to accept shipments from online retailers before ordering. Their compliance team verifies licenses at [email protected].
- Does this work with Ruger 10/22 magazines?
- No, this rifle uses Ruger's proprietary JMX-1 rotary magazine specific to the American Rimfire series. The 9-round capacity magazine inserts flush with the stock and costs $32.99 as a spare. It shares no compatibility with the 10/22's magazine well or feed geometry.
