I have two sets of rings for a CZ 550. Warne 15BM CZ550 30mm Fixed High Matte Rings Warne 1BM CZ550 1" Fixed Medium Matte Rings Both sets were mounted on my rifle and shot one time (about 20 rounds each). New they cost about $50 each. I will sell them for $30 each or $50 for both of them. No charge for USPS shipping to lower 48 states of the US. Beyond that, buyer would pay for additional shipping cost.
