Detailed Features 

Cold hammer-forging produces a consistent bore geometry that directly supports accuracy and extends barrel life. The adjustable trigger lets the shooter set pull weight to their preference, which helps with precision work at the bench or in the field. The detachable magazine makes reloading faster than fixed-mag designs. Two-position push-to-fire safety is positive and unambiguous in operation. 
 
The Turkish walnut stock is a standout feature: it looks good and provides the stability needed for careful shot placement. The 24.8-inch barrel adds velocity to .22 WMR, which matters for small game at extended distances. 
 

Usage Scenarios 

The CZ 457 platform has a swap barrel system, so a .22 LR barrel can be fitted to the same action, making one rifle useful for both rimfire calibers. Small game hunters and target shooters will find the barrel length and accurate trigger system well matched to the demands of 100-yard shooting.

The CZ 457 American .22 WMR consistently draws positive feedback across build quality, accuracy, and trigger feel. The Turkish walnut stock is singled out for both its appearance and ergonomics. Shooters report tight groups at distance, and the adjustable trigger gets credit for the clean pull that supports that accuracy.

The ability to swap barrels between .22 LR and .22 WMR on the same action is mentioned as a practical value-add that reduces the case for owning multiple rimfire rifles. The rifle's ergonomics hold up well for extended range sessions.

Weight comes up occasionally — at 6.17 lbs the 457 is not ultralight — and some users note the price sits higher than comparable rimfire bolt guns. The consensus, though, is that the quality justifies the investment for shooters who want a well-made rimfire that holds its accuracy over time.
