CZ-USA 457 Synthetic Sr .22 WMR 5-Round Rifle

The CZ 457 Synthetic in .22 WMR with 5-round capacity represents a modernized approach to rimfire rifle design, combining CZ's proven platform architecture with refined ergonomics and precision engineering. Built on the same swappable barrel system that established the 455 as a competitive standard, the 457 advances the lineage with a fully adjustable trigger mechanism that allows shooters to dial in weight, creep, and over-travel characteristics to personal preference—a critical feature for precision work at distance or during competitive shooting events.

The .22 WMR cartridge delivers greater velocity and energy retention than standard .22 Long Rifle, making it suitable for small-game hunting and varmint control at extended ranges where subsonic .22 LR performance becomes marginal. The 60-degree bolt lift—a departure from the original 455 design—reduces the arc required for manual cycling and, critically, allows larger objective lens diameters on mounted optics without interference, enabling hunters and competition shooters to use premium glass without compromise. The two-piece interlocking bottom metal provides a rigid platform for the 5-round magazine and serves as the foundation for accessory mounting. Synthetic furniture eliminates concerns about moisture absorption and finish degradation in field conditions, while the weight of 7.13 lbs keeps the rifle manageable during extended field sessions.

This configuration appeals to hunters pursuing medium-range varmint work, precision rimfire competitors, and shooters seeking a modular platform capable of accepting multiple barrel assemblies. The adjustable trigger and optimized bolt geometry address common operational requests from the rimfire precision community. The 5-round capacity aligns with hunting regulations in jurisdictions with magazine restrictions and reflects a practical compromise between firepower and reload efficiency in field use.

The CZ 457 Synthetic .22 WMR occupies a distinct niche: serious rimfire users who prioritize trigger adjustability, barrel modularity, and optic clearance over budget-tier pricing. It competes directly with platforms like the Tikka T1x in the mid-premium rimfire category, offering mechanical advantages that justify its positioning for discipline-specific applications.
