CZ 457 Metal cocking indicator kit

Upgrade Your CZ 457 Bolt

This kit includes 3 parts. A metal (stainless steel) cocking indicator to replace the stock red plastic one and a stiffer firing pin spring and a lighter trigger spring. You can use all these parts in combination with original CZ parts to tune your action to your liking.

Replace the Red Plastic Cocking Indicator with Durable Metal

The first component in this kit is a precision-engineered metal cocking indicator that replaces the stock red plastic part in your bolt. This upgrade isn’t just about aesthetics—it’s about durability and precision. Plastic components can wear down or break over time, potentially impacting the reliability of your firearm. With a metal cocking indicator in place, you gain an upgrade built to withstand regular use, ensuring your firearm remains operational and trustworthy. Compared to the original part, this coking indicator has an extra surface that Extends past the spring. Thanks this precision machined face, the firing pin is no longer driven forward by the spring itself but rather by the cocking indicator. This provides better repeatability and overall better precision. Finally, It makes maintenance of your bolt easier as assembly becomes easies with this part.

Stiffer Spring for Dependable Firing

The second component is a stiffer spring for the firing pin, designed to boost reliability and provide consistent performance. Unlike standard springs, this upgraded option reduces the likelihood of misfires, allowing for smoother operation and increased accuracy with every shot. Please be aware, that due to the design and construction of the CZ 457 action, adding a stiffer firing pin spring will also affect the trigger pull weight. We recommend also adding our softer trigger spring to compensate for this.

Lighter Trigger Spring

The last component in this kit is a softer trigger spring that reduces the pull weight of the trigger by approximately half, compared to the stock CZ trigger spring. More information on the trigger spring can be found here.
