Features 

 
21-inch free-floated barrel: The longer barrel extracts more velocity from .22 WMR than a shorter carbine would, and free-floating it removes stock pressure variability that can hurt consistency. 
 
Semi-automatic action: Fast follow-up shots for small game or reactive target work. 
 
Crossbolt safety: Standard passive safety for transport and storage. 
 
Optic-ready: No iron sights included; the receiver is set up for a scope, which is the practical choice for .22 WMR at its effective ranges. 
 
The .22 WMR chambering puts the RS22 a step above a standard .22 LR rifle in terms of reach and terminal energy on small game, with ammunition that's still affordable compared to centerfire options.

Feedback on the Rossi RS22 in .22 WMR is mixed but leans reasonably positive given the price point. Buyers looking for an affordable semi-auto .22 Mag rifle generally find it delivers on that expectation — it's light, easy to shoot, and handles small game and target work adequately.

Ease of disassembly and cleaning comes up as a positive fairly often.

The reliability complaints are real and worth knowing about: some users report feeding and ejection failures, particularly with certain ammunition brands. This is common enough in the community that new owners are often advised to test multiple ammo types to find what cycles cleanly. The 10-round magazine limit is also mentioned as a downside compared to similar rifles.

Net takeaway: a functional budget .22 WMR semi-auto that works well with the right ammo, but it's not a set-and-forget proposition — it may need ammo experimentation and attention to stay reliable.
