he CZ 457 Factory Barreled Action with OEM MTR Match Chamber is a brand-new, never-fired factory assembly direct from CZ, and it’s one of the easiest and most reliable ways to kick off a precision rimfire build. If you’re looking for a proven foundation that delivers excellent accuracy and flexibility, this barreled action checks all the boxes right from the start.
The CZ 457 builds on the legacy of the incredibly popular CZ 455, a rifle that helped define the modern multi-caliber rimfire bolt-action platform. Shooters loved the 455 for its versatility and accuracy, and CZ took that feedback to heart when designing the 457. The result is a refined platform with improved ergonomics, a modern safety design, a better-adjustable trigger, and the same quick-change barrel system that made the 455 so successful. It’s no surprise the 457 has become a favorite among competitive and recreational rimfire shooters alike.
With its easy caliber-change system, the CZ 457 allows you to move between .22 LR, .22 WMR, and .17 HMR with minimal effort, making it a great choice whether you’re building a dedicated competition rifle or a versatile do-it-all rimfire. The included OEM MTR match chamber offers excellent accuracy potential and consistency, giving you a solid starting point for a high-performance build.
