A better trigger helps you shoot your CZ 457 more precisely, because a clean, predictable break disturbs the rifle less. You can choose two trigger assemblies:
CZ Flyweight trigger assembly: two-stage, fully adjustable, for ISSF style target shooting and precision rimfire. You set the first and second stage travel, overtravel and the blade angle and position. The second stage pull is 0.9 to 1.8 N, about 92 to 184 g. It comes with a target firing pin and a curved duralumin blade, compatible with Anschütz blades.
Timney trigger assembly: single stage, drop-in, with an adjustable pull from about 283 to 907 g (10 oz to 2 lb). You can choose a curved or straight shoe. Made in the US.
