Hello Buckfever...congratulations on that big bear!... Besides the rings mentioned above,rings for the Bruno/CZ's are made by Warne,Lynx Mounts, B-Square and Leupold....Warne and B-Square make low mounts as well as higher mounts...If you get the low mounts you will have to grind a little off on your bolt handle....not a big job at all as that is what I did on several of my Bruno's as I prefer lower rings....I will also have to grid the bolt on my CZ550FS if I use the lower Warne rings on it.....How much you have to grind off depends on the size of the scopes eye objective....I'm using a Leupold 1.5X5 which has a fairly small eye obj. but is a little short in lenght......I think the 1.75X6 would have been a better choice.....
Edit: after looking in another catalog I find that the Lynx Mounts/ Rings seem to be a B-Square model....I'm looking for a set of medium rings myself for a Bruno 21H in 8mm that has a butter knife bolt handle that I don't want to modify.......
