CZ 457
Parts & Upgrades

Some components are shared between the CZ 455 and CZ 457, while others are model-specific. Always check the individual product listing for confirmed fitment before ordering. Where compatibility varies by model or configuration, we note it on the product page.

The CZ 457 family includes different stocks, barrel configurations and models, so not every part fits every configuration. We list fitment information on each product page whenever a part has specific compatibility requirements.

Common CZ 457 upgrades include firing pins, bolt knobs, scope rails, trigger components, bedding hardware, chassis systems and barrels. The best place to start depends on whether your goal is reliability, ergonomics, optics mounting or a larger custom build.

It comes down to grip and feel. Our slim knobs come in spiral, helix and grooved profiles with knurled or smooth finishes, and the XL Finger Groove gives you a full-size knob to grab. Each is listed for the CZ 455 and CZ 457; check the product page for fitment details.

Start with your optic setup and the amount of elevation you need. Rails may differ in MOA angle, height and mounting configuration, so check the specifications on the individual product page before ordering. If MOA selection is unclear, review the rail specifications and your optic setup before ordering; the right choice depends on your intended use and available scope adjustment.

Pete's Pillars manufactures a growing range of CZ 457 components, including firing pins, bolt knobs, scope rails, bedding components, magazine-related parts and replacement hardware.

Check the fitment notes and specifications on the product page first. If the application is still unclear, contact us before ordering and we'll help determine whether we have confirmed compatibility.

No. Along with the CZ 457 parts we design and manufacture, we stock components from other established manufacturers so you can shop replacement parts, upgrades and larger build components in one place.
