Scope mounts for CZ 557 SA

About the company

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.

About the rifle

CZ 557 was introduced in 2012 as an upgrade of the popular CZ 550 centerfire rifle with some notable differences. CZ 550 featured a controlled-feed action but that is no longer the case with 557 which is equipped with a cylindrical push-feed bolt with two locking lugs, a short extractor, and a plunger ejector. The bolt still locks into the receiver. The barrel is cold hammer forged and factory-lapped which provides greater accuracy. While CZ 550 had a set trigger, the 557 comes equipped with a fully adjustable trigger mechanism. It features an internal box magazine with a hinged floorplate whose release is located on the front of the trigger guard. Depending on the variant, the stock can be made of walnut, beech, polymer or laminated wood. The CZ 557 series was discontinued in 2021. It was sold in short-action and long-action models.

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. If the mount has a recoil stopper, it must fit the recoil notch on the receiver. Rifles that have two-piece mounts interchangeable with CZ 557 SA are the following:

  • Brno ZKK 600
  • Brno ZKK 601
  • Brno ZKK 602
  • Brno ZG 47
  • Brunner 19
  • CZ 557 LA
  • CZ 550 Standard
  • CZ 550 Magnum
  • CZ 537
  • CZ 555

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. There are no rifles that have one-piece mounts interchangeable with CZ 557 SA.
