Upgrade Your CZ 457 Trigger With the Timney Replacement
Competition shooters need their rifles to perform reliably and consistently. The finite shifting in the gun from one shot to the next could make the difference between hitting or missing a target, which is why making sure every aspect of the rifle has tight tolerances is necessary.
While the stock CZ 457 Rimfire Trigger is good, Timney saw some areas of improvement. This aftermarket trigger replacement for the CZ 457 Trigger has tight tolerances and a wide pull weight range. These upgrades allow the shooter to customize the trigger to their preference and reliably shoot at these settings every time.
To ensure a high-quality trigger, Timney precision-machines and heat-treats the sear and trigger shoe to 56 Rockwell. The trigger also has a black oxidized coating, and an NP3 coated sear, which provides lubricity and reliable performance.
Timney Sear Engagement, Overtravel and Pull Weight
This trigger features Timney’s Sear Engagement Lock Design. The sear engagement is the amount of movement before the trigger breaks. With the Timney trigger, the shooter can adjust and lock the sear engagement to match their preferences.
Overtravel is any movement after the trigger break. After adjusting the sear engagement, adjust the overtravel by turning the screw either clockwise to increase it or counterclockwise to decrease it. The overtravel on these triggers can range from zero to infinity.
Pull weight can be increased by turning the pull weight screw clockwise and decreased by turning the screw counterclockwise. This trigger comes factory set at 1 lb., but the pull weight can range between 10 oz. and 2 lbs.
