CZ 457 ERGO is a rimfire rifle built on one of the most successful CZ platforms and paired with a more modern, ergonomic thumbhole stock. This version is designed for shooters who want stable grip, better control and a more natural position behind the optic, while keeping the proven strengths of the CZ 457 series.

The model features a fiberglass-reinforced polymer stock with a removable cheekpiece, inspired by the concept of the CZ 600 ERGO. This gives a very good balance of durability, comfort and practical weight. The CZ 457 ERGO is officially fitted with a 525 mm cold hammer forged barrel with factory 1/2x20 threading for muzzle devices, while the platform retains the core CZ 457 features – modularity, 60° bolt lift, adjustable trigger and 11 mm dovetail for optics.

• ergonomic thumbhole stock for a more natural and stable grip;
• fiberglass-reinforced polymer stock;
• removable cheekpiece for better fit with the shooter and the optic;
• 525 mm cold hammer forged barrel with 1/2x20 thread;
• modular CZ 457 platform with user-swappable barrel and caliber concept;
• adjustable trigger and short 60° bolt lift;
• 11 mm dovetail for optics mounting.

In .22 LR, this model is a very good base for training, sport shooting, recreational use and small game applications where legally permitted. The ERGO stock provides more confident control and a more natural hand position, which is especially noticeable when shooting from support, from the bench or with a mounted riflescope.

The CZ 457 platform is known for good mechanical balance and a very well thought-out construction. Official series features include a positive safety, a cocking indicator, the ability to remove the bolt even with the safety engaged, and magazine/barrel compatibility with the CZ 455. These are details that matter in real use.
