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 527 is a smallbore centerfire bolt action rifle that was first introduced in 1990. It utilizes a "mini-Mauser" action system that is optimized for shorter and less powerful calibers and comes equipped with a controlled-feed bolt action with two locking lugs at the front of the bolt that lock into the steel receiver. On the right behind the bolt lever is a fold-down safety catch that must be pushed forward to put the rifle in safe mode. This is indicated by a red dot that reveals itself next to the bolt lever when the safety catch is activated. The magazine catch is located on the right of the magazine, which is detachable and can hold up to five rounds. CZ 527 also features a hammer forged barrel and a single set trigger. Depending on the variant, it featured a walnut, polymer or laminated-wood stock. The rifle was discontinued in 2021.

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 527 are the following:
Brunner 16
BRNO ZKB 680
Brno Fox
Brno ZKM 611
Sako TRG 21/41
Sako TRG 22/42
Steyr SSG 69
Tikka T3
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 527 are the following:
This slip-on fixed mount from the Czech company Kozap is a perfect fit for CZ 527.
This slip-on detachable repeatable mount from the Czech company Kozap is also a perfect fit for CZ 527.
This Picatinny rail is the most fitting on offer since it is made of the same material as the rifle's receiver.
If you happen to own this or any other rifle, we would appreciate it if you could help us expand our database by sending us some photos of the rifle receiver (the bare mounting surface of the rifle without the mounts installed). For your help, our company offers a fair return in terms of practical rewards.
