Take your CZ 457 or CZ 455 to the next level of precision with our premium 24” Drop-In Barrel. Engineered for serious shooters and rimfire competitors, this barrel features a heavy 1.180” straight profile, cut from 416R stainless steel, and is lead-lapped and stress-relieved to ensure top-tier consistency and accuracy.

With a 1:16 twist rate and our proprietary .22 LR WASP chamber, this barrel offers the perfect blend of precision and feeding reliability in a repeating rifle platform. We’ve finished it with a precision target crown instead of threading to eliminate the risk of bore distortion—perfect for those chasing the tightest groups possible.

To ensure optimal fit and performance, we include barrel shims so you can fine-tune your headspace to match your preferred ammunition for peak results.
