HEADS ON RING SCREWS SNAP EASILY EVEN WHEN USING A TORQUE DRIVER AT HALF THE RECOMMENDED PRESSURE. I'M ORDERING MY SECOND SET OF REPLACEMENT SCREWS NOW.
About the only game in town for CZ 452-455 American and Varmint models; European 11mm bases are hard to find.
Pros: FIT NICELY; WORK ON CZ452/3'S AND CZ455"S
Cons: RING SCREWS ARE VERY SOFT; RINGS ARE EXPENSIV E
