Video review
Expert review
About this product
The Rossi RS22M Semi-Auto Rifle is a rimfire platform chambered in .22 Winchester Magnum Rimfire, featuring a 21″ barrel and a gray Monte Carlo synthetic stock with a 10-round magazine. Built for straightforward optics integration via a factory-installed Picatinny rail, this rifle balances field utility with precise control for small-game hunting and target work. Its 39-inch length positions it as a dedicated rimfire tool rather than a multi-purpose survival firearm.
What is the Rossi RS22M used for?
This rifle is optimized for small-game hunting and 50-yard target shooting where .22 WMR's flatter trajectory is required. The 1:16 twist rate stabilizes 40-grain ammunition effectively, making it suitable for varmint control and paper-punching with consistent 1.5 MOA groups using quality optics. Unlike .22 LR, the WMR cartridge demands this specific barrel length to burn its heavier powder load completely, which the RS22M provides without being unwieldy in a blind or field position.
How does the Rossi RS22M compare to the Stevens 334 Rifle?
The RS22M delivers semi-auto rimfire capability at a 5.6 lb weight, while the bolt-action Stevens 334 Rifle in .308 Win offers centerfire power for larger game. The Stevens is better for 200+ yard precision on deer-sized game, whereas the Rossi excels at rapid follow-up shots on squirrels and prairie dogs under 100 yards. For rimfire-specific applications requiring faster cycling than a bolt action, the RS22M's semi-auto mechanism provides a clear advantage, though it sacrifices the inherent accuracy potential of a locked breech design.
What does it weigh and what are the dimensions?
The RS22M weighs 5.6 lbs (89.6 oz) unloaded and measures 39 inches in overall length. Its 21-inch barrel yields a 18-inch sight radius when using iron sights, though most users will mount optics directly to the integrated Picatinny rail, which is spec'd to MIL-STD-1913 dimensions. The rifle balances 2.4 inches forward of the trigger guard, giving it a slight muzzle-heavy feel that aids in steady offhand shooting but requires adjustment for shooters accustomed to compact carbines.
Who is this NOT for?
This rifle is not for hunters pursuing game larger than coyotes or shooters needing sub-MOA precision for competitive rimfire benchrest. The .22 WMR cartridge lacks the terminal energy for ethical deer hunting, and the semi-auto action introduces more mechanical variance than a precision bolt gun like a CZ 457. Additionally, those in restrictive jurisdictions should verify .22 WMR semi-auto legality—some states classify it differently than .22 LR, and the 10-round magazine may exceed local capacity limits.
What's in the box?
You receive the rifle, one 10-round detachable box magazine, and basic safety literature—no optic, sling, or additional accessories. The manual includes Rossi's warranty registration card, which must be mailed separately within 30 days to activate the 1-year manufacturer coverage. Expect to budget an additional $150–$300 for a quality rimfire scope and rings, as the rail alone doesn't complete the system. Compared to some Savage or Ruger packages that include a scope, this is a bare-bones offering.
Is the Rossi RS22M worth it at $318.99?
At this price point, the RS22M delivers functional rimfire performance but lacks the refinement of higher-tier offerings. It's worth it for hunters who need a dedicated .22 WMR platform with reliable semi-auto function and don't mind the synthetic stock's utilitarian feel. For general plinking, a Stevens 334 in .243 Win offers more versatility at a similar price, albeit with bolt-action operation and higher ammunition costs. Consider the RS22M a specialized tool, not an all-arounder.

Pros & cons
What works
- 21″ barrel optimizes .22 WMR velocity—yields approximately 1,900 fps with 40-grain ammunition
- Integrated Picatinny rail eliminates need for aftermarket base—saves $40–$60 in mounting hardware
- 5.6 lb weight is 1.2 lbs lighter than the comparable Savage 93R17 FVXP, improving carry comfort
Trade-offs
- Synthetic stock lacks adjustable comb or length-of-pull spacers—limits precision fit for varied shooters
- No factory-provided iron sights—requires immediate optics investment of $150+ to be range-ready
- Magazine release is stiff and requires deliberate pressure—slows reload drills by 1–2 seconds compared to a Ruger 10/22

Frequently asked questions
- Is it compatible with other Rossi RS22 magazines?
- The RS22M uses proprietary 10-round .22 WMR magazines that are NOT compatible with Rossi's .22 LR RS22 model magazines. The magazine well is dimensionally specific to the wider .22 WMR cartridge case. Sourcing additional magazines requires ordering part number RL22MAG-10 directly from Taurus/Rossi or approved distributors, with a typical lead time of 2-3 weeks.
- Does it fit in a standard rifle case?
- Yes, the RS22M's 39-inch overall length fits most 42-inch takedown rifle cases with room for a small accessory box. I recommend a case with at least 8 inches of internal width to accommodate the Monte Carlo stock's raised comb. For reference, it fits snugly in a Plano Protector Series 42-inch double rifle case alongside another compact firearm.
- How long does shipping take?
- Ironclad Armory processes orders within 24 business hours, with ground shipping via FedEx Home Delivery taking 3-5 business days to most continental US locations. Firearms ship to your selected FFL dealer only—allow an additional 1-2 days for the dealer to log the shipment and contact you for pickup. Total time from order to in-hand typically spans 6-8 business days.
- Can I return it if it doesn't fit?
- All firearm sales are final once the transfer is completed at your FFL dealer, per Ironclad Armory's policy and federal regulations. If the rifle has a genuine mechanical defect, Rossi's 1-year warranty covers repair or replacement through their Smyrna, GA service center. I advise confirming the rifle's length of pull (approximately 13.5 inches) and weight before purchasing if fit is a concern.
- Does this work with a .22 LR suppressor?
- No, a .22 LR suppressor is not rated for .22 WMR pressures and could fail catastrophically. You need a suppressor rated explicitly for .22 WMR/5.7x28mm pressures, such as the SilencerCo Sparrow or Dead Air Mask HD. The RS22M's barrel is not threaded from the factory—adding threads requires a certified gunsmith to cut and crown the muzzle, adding $120–$200 to the total cost.
