Description
Finding a semi-auto chambered in .22 WMR used to mean spending serious money or settling for something finicky. The Rossi RS22M changes that math. It takes the proven blowback design from Rossi's popular RS22 line and pairs it with the flatter-shooting, harder-hitting .22 Magnum cartridge, giving you noticeably more reach and authority than a standard .22 LR without adding recoil worth mentioning. At 5.6 pounds it carries easily on a walk through the squirrel woods, and the 10 round detachable magazine keeps you in the action with quick reloads.
A Free-Floated, Threaded Barrel That Earns Its Keep
The 21 inch barrel is the heart of this rifle. It's free-floated from the stock, so pressure on the forend won't wander your point of impact, and owners regularly report tight groups at 50 and even 100 yards once they find the load their rifle likes. The muzzle comes threaded 1/2×28 from the factory, which means adding a suppressor or other muzzle device is as simple as spinning one on. A quiet .22 Magnum with subsonic-friendly hearing protection benefits is a genuinely fun way to spend an afternoon.
Set Up the RS22M Your Way
There are no iron sights on this model, and that's by design. The receiver wears a rail up top so you can mount a scope or red dot and get the most out of what the .22 WMR cartridge can do at distance. The black synthetic Monte Carlo stock is textured for a sure grip in wet weather, shrugs off dings and scratches, and puts your eye right in line with a mounted optic. A crossbolt safety sits where your trigger finger expects it.
Where the Rossi RS22M Fits
This is a rifle for the practical shooter: pest control out past where a .22 LR gets iffy, small game hunting, steel plates at the range, or a suppressor host that doesn't break the bank. It cycles a wide range of bullet weights reliably, the trigger is better than you'd expect at this level, and the whole package is light enough that new and seasoned hands alike will enjoy running it.

Frequently Asked Questions
Is the Rossi RS22M suppressor ready?
Yes. The 21 inch barrel comes threaded 1/2×28 from the factory, which is the standard rimfire pitch, so most .22 caliber suppressors and muzzle devices will thread right on. No gunsmithing required, just remove the thread protector and attach your can.
Does the RS22M come with sights?
No, this model ships without iron sights. The receiver is optic ready with a rail on top, so plan on mounting a scope or red dot before heading to the range. Given the extended reach of the .22 WMR cartridge, a decent rimfire scope is the way to get the most out of this rifle.
How accurate is the Rossi RS22M?
Owners consistently report strong accuracy for the class, with tight groups at 50 yards and respectable performance out to 100 once a favorite load is found. The free-floated barrel helps keep point of impact consistent regardless of how you rest the forend. Like most rimfires, it pays to test a few bullet weights to see what your particular rifle prefers.
What's the difference between the RS22M and the standard RS22?
The RS22M is chambered in .22 WMR, while the standard RS22 runs .22 LR. The Magnum version delivers a flatter trajectory, more energy on target, and better performance at longer range, which makes it a stronger choice for varmints and small game past typical .22 LR distances. This particular version also adds the threaded 21 inch barrel and optic-ready receiver.
