CZ 457 Ergo .17 HMR, barrel 525mm thread 1/2x20

The CZ 457 ERGO in .17 HMR calibre combines the proven technology of the CZ 457 platform with a modern, ergonomic thumbhole stock inspired by the design of the CZ 600 ERGO. This model is aimed at shooters seeking high comfort, excellent control and precise shooting performance in a contemporary appearance.

The fiberglass-reinforced polymer stock in thumbhole style offers a natural, relaxed hand position and high stability at low weight. The removable cheek piece allows individual adjustment to the shooter and ensures a reproducible cheek weld – ideal for both sporting shooting and hunting applications. The robust construction guarantees durability even under intensive use.

The CZ 457 ERGO is fitted with a cold-forged barrel measuring 525 mm in length (20"), which makes optimal use of the ballistically powerful .17 HMR calibre. The muzzle thread 1/2×20 allows the fitting of suppressors or other muzzle devices. The model is available with or without mechanical iron sights:

• With Iron Sights for classic open-sight shooting

• Without Iron Sights as a consistently optics-oriented variant for scopes

  On the version with iron sights, the mounting openings can be neatly closed with the included plugs after removing the sights.
