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 527 Rifle Review

The Brno CZ 527 is a smallbore centerfire bolt action rifle that utilizes a "mini-Mauser" action system which is optimized for shorter and less powerful calibers. It comes equipped with a controlled-feed bolt with two locking lugs at the front of the bolt that lock into the steel receiver. When the CZ took over the production of the rifle, the Brno labels were removed from the receiver; however, the 527 markings remained the same.

Brno CZ 527 comes with a safety catch which is located on the right side behind the bolt lever and must be pushed forward to put the rifle in safe mode. The safety also comes with a red dot indicator that lets the user know when the rifle is cocked and ready to fire.

The Brno CZ 527 also comes with a detachable box magazine that can hold up to five cartridges. The magazine catch is located on the right of the magazine, making it easy to load and unload the rifle.

In addition to its practical features, the Brno CZ 527 also boasts a hammer-forged barrel, which adds to its overall durability and accuracy. It also comes with either single or double set-triggers, giving the user the option to choose the trigger that best suits their shooting style.

Overall, the Brno CZ 527 is a reliable and well-designed rifle that is suitable for a variety of shooting needs.
