Options for reworking a CZ52?

[Kendal Black]

I'm not familiar with the chamber conversion mentioned. I suppose it is the same kind of chamber insert deal the Navy tried, to shoot 7.62 NATO in Garands made for the .30-'06. This is a not the finest idea anyone ever had.

My tendency would be to stay away from it, because once you get the chamber shortener in there, and are hoping it will stay, you still have the old magazine...
