CZ 457

Lore & Background

The CZ 457 was designed to improve on the popular CZ 455 rifle family. Notable changes include the inclusion of a push-to-fire safety in line with the barrel, replacement of the 455's stamped steel unitary bottom, and a reduction in bolt rotation from 90° to 60°. Trigger adjustment is also claimed to be improved. The barrel of the CZ 457 can be easily changed and replaced with other barrels designed for rimfire ammunition.

The rifle features a 60° breech lever opening, a barrel and receiver with anti-corrosion surface treatment, the possibility of dry firing without damaging the firing pin, a side safety (push and shoot type), and an arming indicator. The charger is compatible with models CZ 452 and CZ 455. Given the removable barrel, commonality with the CZ 455, and a compact trigger group, aftermarket parts are available both in the American and European sporting market. There are also different scope mount rings or rimfire scopes compatible with the CZ 457.

Reader's Guide

The CZ 457 represents a refinement of the CZ 455 lineage, with engineering changes focused on safety, ergonomics, and modularity. Its push-to-fire safety aligned with the barrel and reduced bolt rotation are practical improvements for shooting sports. The ability to easily change barrels allows the rifle to be adapted to different rimfire calibers, and the compatibility of its charger with earlier CZ 452 and CZ 455 models ensures continuity for users of those systems. The availability of aftermarket parts in both American and European markets, along with compatible scope mounting options, supports its use in competitive and recreational shooting. The rifle's accuracy has made it widely adopted in shooting sports, and its design features—such as the adjustable trigger and anti-corrosion surface treatment—contribute to its utility. The CZ 457 stands as a direct successor to the CZ 455, incorporating lessons from that platform while maintaining interchangeability with its predecessors.

Did You Know?

• The CZ 457 has a 60° bolt rotation, reduced from 90° on the CZ 455.
• The rifle can be dry fired without damaging the firing pin.
• Its charger is compatible with CZ 452 and CZ 455 models.
• The barrel is easily changeable and replaceable with other rimfire barrels.

Design Philosophy & Engineering Evolution

The CZ 457 was conceived as a deliberate refinement of the well-regarded CZ 455 platform, addressing several design choices that shooters had found limiting. Česká zbrojovka Uherský Brod, the Czech manufacturer behind the rifle, replaced the 455's stamped steel unitary bottom with a more robust construction and repositioned the safety mechanism into a push-to-fire design aligned in line with the barrel. Perhaps most noticeably, the bolt rotation was cut from a full 90-degree throw down to just 60 degrees, tightening the cycling rhythm for competitive shooters. Trigger adjustment was also reworked and claimed to offer smoother, more precise tuning. The rifle is offered as a magazine-fed bolt-action rimfire repeater, chambered in .22 LR, .22 WMR, and .17 HMR, giving owners flexibility across a range of rimfire cartridges. In the United States, the platform reaches the market through CZ-USA, the dedicated import arm for the brand.

Modularity & Aftermarket Ecosystem

One of the CZ 457's most practical strengths is its modular architecture. The barrel is designed to be swapped out easily and replaced with any other barrel engineered for rimfire ammunition, a feature that lets a single receiver serve multiple calibers or performance goals. This interchangeability is reinforced by deliberate commonality with the CZ 455, meaning components and chargers are cross-compatible across the two models, and the 457's charger also fits the CZ 452. The compact trigger group further simplifies maintenance and part sourcing. Because of these shared design elements, a healthy aftermarket ecosystem has developed in both the American and European sporting markets, offering replacement parts, alternative barrels, and accessories. Scope mount rings and dedicated rimfire scope bases are available that are specifically compatible with the 457's receiver profile, so shooters can add optics without resorting to improvised solutions. For a competition or precision-oriented rifle, this level of parts availability and interchangeability significantly lowers the barrier to customization and long-term upkeep.

Trigger, Safety & Practical Features

Beneath the 457's clean exterior sits a suite of features aimed squarely at precision shooting. The trigger is fully adjustable, with pull weight tunable anywhere from 900 grams up to 1500 grams and overtravel bump adjustable from 0.5 mm to 5 mm, giving shooters fine-grained control over their release. The safety is a push-and-shoot type positioned on the side, and an arming indicator provides a clear visual confirmation of the rifle's status. The breech lever opens through a 60-degree arc, and the entire action sits under a metal guard for added rigidity. Both the barrel and receiver receive an anti-corrosion surface treatment, extending service life in humid or outdoor conditions. Notably, the action tolerates dry firing without risking damage to the firing pin, a small but welcome detail for range-side practice. These elements collectively make the 457 a shooter-friendly platform that rewards careful tuning while remaining mechanically straightforward.

Sporting Role & Family Context

The CZ 457 occupies a specific and respected niche in the world of rimfire competition and target shooting. Its reputation rests largely on accuracy, and the rifle is widely used in organized shooting sports where consistent, repeatable performance is the primary currency. It belongs to a broader family of Czech rimfire rifles that includes the CZ 452, CZ 453, and CZ 455, each sharing the magazine-fed bolt-action repeating architecture but differing in specific design details. The 457's position in this lineage is that of the most refined iteration, incorporating lessons learned from its predecessors while retaining the core mechanical philosophy that made the earlier models popular. Manufactured by Česká zbrojovka Uherský Brod and distributed in the United States through CZ-USA, the platform bridges European engineering tradition with the demands of the North American competitive shooting community. Its multi-caliber chambering options and parts commonality with sibling models further cement its role as a versatile, long-term companion for dedicated marksmen.
