Burris Signature Z rings on Kidd rifle

[loganchieftain]

Received my Kidd 22 today and I must be missing something. The rings won't slide on the base from the end. They are unlike any rings I've used before, the entire lower half of the rings have no moving parts. There is a cutout slot in the lower half of the rings that looks to maybe faciliitate compression as the lower screw is tightened when they are on the base. Anybody familiar with these and how they go on the base? Thanks

I insert a screwdriver in that slot and twist it just enough to spread the "legs" a little wider, then the rings will slide onto the base.
