I have a set of CZ mounts on my 375 with a leupold 1-4 VXII. After removing my 3x9 from this gun a couple of times, I have buggered up the soft screws. Anyone know where I can get a set of screws or have experience with the Leupold mounts? I have a set of mounts for my cz 452, I wonder if those screws will fit the cz550 mounts?

Any decent hardware or auto parts store ought to have them.

I forget the size (it's metric), but I have bought just what you're looking for at such places. I would recommend that your replacement ring screws be hardened, hex head screws (or torx head screws, if you can find them, but they can be harder to find).

Just take one of the CZ factory issued screws along and match it up.

I have also replaced the slotted head CZ base screws with hardended, hex head screws.

Thanks mrlexma, great info. Thanks, I appreciate your advice.
