Installed on rossi rs22 easily and without modifications or adjustments. - ProMag Mossberg International 702 Plinkster Tactical Folding Stock

Yes, this will fit a Rossi RS 22 without any issues. The only thing different is the there is no way to use the rear action screw. You remove the bolt in the grip and it is basically clamped instead of using the rear screw. I haven't shot it so I can't really say if that will affect accuracy. The rifle was surprisingly accurate before so I hope that doesn't change. I bought the stock because I was shooting the rifle less and just wanted to make something different than my bolt action and 1022.
