Features 

The 21-inch barrel gives .22 WMR enough velocity to be effective on small game at reasonable distances. The detachable magazine reloads quickly during extended range sessions. The polymer stock uses durable materials that hold up to field use, and the crowned muzzle helps maintain bullet stability at the muzzle exit. 
 
The dovetail rail accepts most rimfire-compatible optics. Both the crossbolt and trigger safeties are standard controls that operate predictably.

The Rossi RS22 in OD Green/Black gets positive marks for its price-to-performance ratio. Owners find the semi-automatic action reliable for range use and small game, and the OD Green finish has a clean tactical look that's well-liked.

On the critical side, accuracy at longer distances comes up fairly often -- the RS22 works well for close-range plinking but some owners find it less consistent when pushing distance. Feeding issues with certain ammunition brands get mentioned occasionally. A few shooters find the trigger pull heavier than they'd prefer. These are the expected trade-offs at this price point, and most owners are satisfied overall.
