I missed the first run of 22LR in these. I've called CZ twice in the last month. Another run of .22LR is coming soon. Which also made me think of the 22WMR. They offer the barrel conversions on their site. When I called yesterday I inquired about the conversions being amib.....rep didn't 100% know. I would hope there isn't an extractor cut in the shank that is bolt hand specific and would think the conversions are universal.
It's a direction I would look into if I can luck into either the 22 or 22 Mag.
