About the CZ

CZ firearms or CZ (which stands for Česká zbrojovka) is based in Uhersky Brod, a small town in the southeastern Czech Republic. CZ has its start in 1936 as a subsidiary of CZ Strakonice, which was itself a subsidiary of Zbrojovka Brno. The arms industry was growing quickly in Czechoslovakia at the time, and Uhersky Brod was chosen since it was secluded and lay beyond the range of German bombers, which, in case of an invasion, would target the arms factories first. The factory initially mostly produced pistols and small-caliber rifles; however, when German forces occupied Czechoslovakia in 1939, the company was renamed to Böhmische Waffenwerke and was forced to make machine guns, such as LK-30 and MG-17, for the German military.

After the end of World War II, the Soviets gained control of the region and the company was nationalized by the communist government, producing air weapons, machine guns, submachine guns, motorcycle and sewing machine parts. In 1957 the company started production of the Model 58, and in 1961 they introduced the world-famous Model 61 Škorpion machine pistol. The year 1975 marked the release of yet another popular model, the CZ 75 pistol which many manufacturers have since used as basis for their own products.

CZ once again became an independent company in 1992 following the fall of the Soviet Union. In the decades after, they have continued production of a variety of weapons seizing the market of law enforcement and military firearms with service pistols, assault rifles and grenade launchers with which they also helped equip the Czech army. They have strived to widen their presence on the international markets, opening a facility for assembly and repairs of CZ pistols in Peru and spreading production of their firearms (certain models of the CZ-P10 pistol) to the United States in 2019. As of 2021 they employed around 1500 workers.

CZ 457 Rifle Review

CZ 457 is a bolt-action rimfire rifle first introduced in 2019 as a replacement for the CZ 455 rifle series, which was itself an upgrade of the old 452 series. It features a cold hammer forged barrel and a controlled-feed action with one locking lug locking the bolt into the receiver. The bolt throw is just 60 degrees, making the rifle more compatible with larger scopes. CZ 457 features a two-position safety which, when pushed forward, puts the rifle in fire mode and reveals a red dot on the right side of the receiver. The safety locks the trigger but not also the bolt, which allows the rifle to be loaded or unloaded even with the safety activated. Depending on the variant, it comes with a stock made of laminated wood, polymer, beech or walnut. All variants come with an adjustable, single-stage trigger and a five-round magazine.

Which rifles have interchangeable mounts

Two-piece mounts

For two-piece mounts to be interchangeable the mounting surfaces of the rifles must match in every dimension except the action length which can vary. This is because the distance between the two pieces of the mount is not fixed. Rifles that have two-piece mounts interchangeable with CZ 457 are the following:

CZ 452 (11 mm)
CZ 453 (11 mm)
CZ 455
CZ 511
CZ 512
CZ 513

One-piece mounts

The necessary condition for rifles to have one-piece mounts interchangeable is that the mounting surfaces of these rifles match in every dimension. Rifles that have one-piece mounts interchangeable with CZ 457 are the following:

CZ 452 (11 mm)
CZ 453 (11 mm)
CZ 455
CZ 511

Our recommendations for mounts

Fixed mounts

This is the only one-piece mount available for CZ 457 and it is made by Kozap. Kozap is also from the Czech Republic, so their Slip-on mount is a great fit for a CZ rifle.

Detachable repeatable mounts

There are not a lot of detachable repeatable mounts available for CZ 457, but these roll-off rings from Rusan are a good choice in terms of price and quality.

Picatinny rails

This Picatinny rail is a good choice in terms of price and quality.
