CZ 457 ERGO is based on the popular and proven modular CZ 457 platform, upgraded with a new thumbhole (ergonomic thumb opening) stock, inspired by the CZ 600 ERGO design. The polymer stock, reinforced with fiberglass and equipped with a detachable cheek piece, provides exceptional comfort and high durability, while maintaining a very comfortable weight.
CZ 457 ERGO is equipped with 525 mm cold-hammered barrels with a standardized thread for mounting muzzle devices. Available in a version with mechanical sights or without sights, which is ideal for mounting a riflescope. In the version with mechanical sights, the mounting openings after removing the sights can be closed with the included plugs.
