Lighter trigger spring kit from CJ Manufactory for CZ 457 models.
A set of springs used to reduce the resistance of the CZ 457 trigger and increase its accuracy.
Specification of the spring kit
The set includes two springs, with the trigger spring reducing the factory pull of the trigger by -50% and the striker spring, which has a 10% higher pull. Using the trigger spring, you can reduce the trigger pull to 0.5 kg.
A stronger striker spring, on the other hand, speeds up the operation of the firing pin and thus contributes to a shortening of the firing time and a greater consistency of ignition of the match composition.
The whole set therefore serves not only to reduce the of the CZ 457 trigger pull, but also to increase the accuracy of the CZ 457 rifle.
The springs as they come are made to fit .22 LR. However, with a slight modification they can be made to work also with .17 HMR / .22 WMR caliber. The modification requires sanding down both ends of the springs by approximately 0.5mm.
