Boyd, unfortunately Ruger does not make a .22wmr cylinder for this revolver.

Boyd, at the moment Ruger does not make a 22 mag cylinder for this, hopefully in the near future they will. I've heard of people using the Ruger single six cylinders. They fit but the timings off, so you would have to find a qualified gunsmith to properly time it for you. Sorry but hope this helps.

Boyd, unfortunately no Sir. The Single Six cylinders will fit within the frame wide window but the timing is off and they won't just drop in and work. This is likely by design so folks don't do as you're considering and try to use a Single Six 22 Mag cylinder in their Wrangler and make it a convertible. So far it seems Ruger is not planning on a Wrangler convertible and there is only speculation on reasons why. Cheers and stay safe!
