Fits All CZ-457's
Replacement Action Screws
TORX drive action screw "Kit" for the CZ 457. Makes repeating the action torque simple and easy. The #20 TORX drive helps to eliminate the rolled edges on the head of the screws Allen wrench can cause.
When bench testing your CZ we recommend you start your action screw torque at about 18 inch pounds and work up from that point 2 inch pounds at a time until you find your best group size but no more then 28-30 inch pounds. Our experience has found that a 20 inch pound torque seems to work well with most available ammo.
