The new CZ 457 family is distinguished by its highly sophisticated modular design. In comparison with existing models and rival products, it brings considerable improvements in all key parameters, whether we are talking about user safety, precision or lifetime.To a greater or lesser extent, the concept of many of the new CZ rimfire rifles returns to the original reason this category of firearms was created in the first place and why they have enjoyed great popularity for such a long time. Rimfire rifles are often sought by owners of hunting rifles, especially for practice, fun or for teaching the younger generation the basics of shooting and hunting. In this respect, the design of the new CZ 457 family is remarkable. The partial integration of the design and some parts with the successful CZ 557 rifle series has been a great move, particularly with respect to the fully adjustable trigger mechanism with exceptional properties.
It is also worth stressing that this series has retained the successful CZ 455 magazines and barrelled action which means that owners of these weapons have an option of an easy and affordable generational modification.
The advantages of the CZ 457 can be divided into three main areas:
Today, the prevailing way of operating long firearms is the so-called positive safety which also features on the CZ 457 guns in the form of a lever on the right-hand side of the receiver. The safety is released by moving the lever forward, exposing a red dot on the side of the receiver that indicates that the rifle is ready to fire.
A new element in CZ rimfire rifles is the striker status indicator, which visually and by touch shows the status of the striker mechanism: when the striker is cocked, a small red indicator protrudes from the rear of the bolt.
An additional benefit for safer handling is the separate bolt extractor control on the left side of the receiver. It is therefore not necessary to depress the trigger at all when stripping the gun for basic maintenance.
Last but not least, once again in keeping with the current preferences of most shooters, the CZ 457 guns allow the bolt be opened and extracted with the safety on.
In general, CZ rimfire rifles are highly accurate, however, the truth is that the design legacy of the CZ 452 ZKM limited the options to modify the trigger mechanism parameters. CZ has already managed to solve this problem in several variants of the CZ 455 family. As a result, the company has introduced a new trigger mechanism for the CZ 457 family. It allows the user to adjust the trigger pull weight within a very favourable range of 8 to 15 N, the trigger travel may be adjusted between 0.5-7 mm. Basically, the shooter has the option to use the gun for ordinary training as well as a target special in its category.
One element which is often overlooked but which plays an important role in accuracy is the weight of the striker. In comparison with previous models, the weight of CZ 457 rimfire rifle strikers has been reduced by more than 60%, resulting also in a faster strike and at the same time less shock when fired.
Where stocks are concerned, there has been a great improvement in all long guns from CZ, which has also been reflected in the new rimfire rifles. For the CZ 457 series, Ceská zbrojovka has developed a new type of bedding which allows constant tightening of the screws in the barrelled action within the stock. Improvements have also been made with ergonomics, this new series therefore has an extremely comfortable and reliable grip.
In the CZ 457 MTR in .22 LR cal. target model, a so-called ‘Match’ chamber has been used with dimensions on the tightest limit of allowable parameters. In combination with the other upgrades, this rifle guarantees 15 mm groups at a distance of 50 m!
