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 ZKB 680 Fox Rifle Review

Brno ZKB 680 Fox is a bolt action rifle manufactured by Zbrojovka Brno, Zbrojovka Kulovnice and by the CZ company. Brno also introduced the Fox model 2 with some minor design changes; however, it was eventually replaced by the CZ 527. The rifle is primarily intended for hunting and sporting purposes. With a weight of only 2.6 kg (5.7 lbs), it weighs no more than an ordinary smallbore rifle.

The breech mechanism is based on Mauser design using a controlled-feed bolt head with two locking lugs at the front of the bolt that lock into the steel receiver. The rifle was developed from the ZKW 465 by lengthening the barrel and reducing the weight of the weapon.

It comes equipped with a collapsible, height-adjustable back sight and a replaceable foresight. Moreover, on the top of the receiver, there are 16.5 mm flat-top dovetail grooves, which are suitable for installing scope mounts. The double-set trigger comes with a spring spanner and can be weight-adjusted by the users by turning a small screw positioned inside the trigger guard. Positioned on the right-hand side behind the breech cocking handle is a two-position safety catch that must be pushed upwards to put the rifle in safe mode. The magazine is detachable and can hold up to 5 rounds. It can be removed by pressing a small release button on the right side of the forearm.

Brno ZKB 680 Fox Calibers

The rifle is chambered for the following calibers:

.22 Hornet
.222 Rem.

Brno ZKB 680 Fox rifles come with 16.5 mm dovetail grooves at the top of the receiver which are suitable for installing scope mounts. Some models come with the recoil notch on the left rear side of the receiver and some models do not. Since the recoil of .22 Hornet and .222 Rem. calibers is fairly mild, the notch is not vital.
