The History of Brno

The history of the Brno company or Czechoslovak Armory (Československá zbrojovka) as it was known prior to WWI, began in the city of Brno in the Czech Republic, formerly known as Czechoslovakia. In 1918, the Brno Rifles factory was established. Before 1918, Brno Plant was an arsenal located in the Austro-Hungarian Empire. Brno started producing Mauser 98 rifles in 1920 after buying excess weapons and equipment from Mauser-Oberndorf. These Brno-produced Mausers had a 98/22 designation stamped onto the receivers marking the year of production.

In the period between WWI and WWII, Brno collaborated with the Royal Small Arms Factory in Enfield, England to develop a well-known Bren light machine gun. They produced weapons for the Czechoslovakian and German armies during World War II. After the war, the company was nationalized by the Czechoslovakian government and renamed Zbrojovka Brno. While it was under socialist control until 1989, it switched to the production of sporting weapons which quickly gained a reputation for their reliability. For some time, the company also produced light artillery and several other products such as tractors, typewriters, and early computers.

During the years they presented numerous models of weaponry such as the ZB vz. 26 light machine gun, ZB-50 heavy machine gun, the MG34, several bolt action rifles, ZKM and ZH series, ZKR 551 handgun etc.

The company was privatized in 1990, just three years before Czechoslovakia split into the Czech Republic and Slovakia. Zbrojovka Brno was acquired by Česká zbrojovka (CZ) in 2008. With the new ownership, they agreed to a longer lease, which allows the business to continue production in rented facilities. They still make high-end products for hunting and competition, including pistols, single-shot and double rifles, combination rifles, as well as over/under shotguns.

Brno CZ 537 Rifle Review

The Brno CZ 537 is a bolt-action rifle that was first introduced in 1989. Production continued until 1995, with the production of finishing pieces running until 1999. A total of 15,000 of these rifles were made. Model 537 was eventually replaced by the CZ 550 series.

One unique aspect of the CZ 537 is its ability to be fitted with either a detachable or internal magazine. The detachable magazine has a capacity of four cartridges, while the internal one can hold up to five. The magazine itself is adapted from the Brno CZ 531. Another notable feature of the CZ 537 is its safety catch, which is positioned on the right of the receiver, just behind the bolt lever. This placement makes it easy to access and operate.

In addition, the receiver on the CZ 537 comes with 19 mm dovetail grooves for scope mounting purposes. This makes it easy to add a scope to the rifle, allowing for more accurate shots at longer ranges.

Finally, the CZ 537 is equipped with a set trigger that can be used as either a regular trigger or a hair trigger. The hair trigger is activated by pushing the trigger lever forward, which reduces the weight of the pull and allows for a more sensitive trigger.
