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 ZG 47 Rifle Review

The Brno ZG 47 is a bolt action rifle that was first introduced in the 1950s. It was produced until 1966/67, when it was replaced by the ZKK series. Despite its age, the ZG 47 remains a popular choice among shooters thanks to its reliable action based on the Mauser 98 design.

One notable feature of the ZG 47 is its forward rotating safety, which is positioned on the right side of the bolt shroud while the ZKK’s safety catch is attached to the receiver. This allows for easy access and use, making it a convenient feature for shooters. There were both standard and lightweight versions of the ZG 47 available, giving shooters the choice between a heavier or more portable rifle. In contrast to the ZKK, the trigger on the ZG 47 is only partially linked to the receiver.

One key difference between the ZG 47 and the ZKK series is in the sight system. The ZG 47 features a barrel-mounted backsight with screw adjustable windage, whereas the ZKK version is tapped from side to side. The ZG 47 also has a finer finish compared to any ZKK models, making it a more aesthetically pleasing choice for some shooters.

Both the ZG 47 and the ZKK models come with a replaceable bead foresight. The receiver is grooved for the standard 19 mm CZ mount meaning that the ZKK 600 one-piece mounts can also be used with the ZG 47 and the standard-length CZ 550. The bottom floorplate of the internal magazine is hinged and controlled by a latch on the inner side of the front trigger guard housing.

One standout feature of the ZG 47 is its finely tunable trigger mechanism, making it a popular choice for shooters looking for precise trigger control. Additionally, the rifle is equipped with a non-rotating extractor.
