CZ 457 explained

The CZ 457 is a series of magazine-fed bolt-action rimfire repeating rifle manufactured by the Czech firearms manufacturer Česká zbrojovka Uherský Brod and imported into the United States by CZ-USA.^{[2] [3]}

The barrel of the CZ 457 can be easily changed and replaced with other barrels designed for rimfire ammunition. Given the removable barrel, commonality with the CZ 455, as well as a compact trigger group, aftermarket parts are available both in the American and European sporting market.^[4]

The CZ 457 is widely used in shooting sports due to its accuracy.

History

The CZ 457 was designed to improve on the popular CZ 455 rifle family, notably the inclusion of a push-to-fire safety in line with the barrel, and replacement of the 455 stamped steel unitary bottom. Bolt rotation was also reduced to 60° from 90° in the 455. Trigger adjustment is also claimed to be improved. The rifle (with its respective barrel) can be chambered for .22 LR, .22 WMR & .17 HMR.^[5]
