BRNO ZH 324

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 ZH 324 Rifle Review

Brno ZH marks the series of combination rifles and shotguns manufactured by Zbrojovka Brno and later by the CZ company. Apart from minor finish differences and being chambered for various caliber options, the structural design remains the same throughout the series.

Brno ZH 324 has a robust locking mechanism with strong hatches on both sides that lock into place when the bascule is closed, providing extra safety. The rifle is based on the ZH 304 model and is chambered for the same 7x57R rifle caliber; however, it uses 16-gauge shotgun shell instead of the 12-gauge one that is found on the ZH 304.

ZH 324 is opened and loaded by pushing the lever on the upper rear side of the action to the right which is a common feature in almost all combination weapons. The upper barrel is chambered for standard rifle calibers and the lower barrel for shotgun calibers – although it is usually the other way around. Another interesting feature is the arrangement of the two triggers. The front trigger only activates the upper barrel whereas the rear one has the option to activate both – first the lower and then the upper barrel. This allows for faster repetitive shots, especially when using a shotgun barrel configuration. The rear one comes set at a pull weight of 1900 g (4.1 lbs) for the upper and 2500 g (5.3 lbs) for the lower barrel, whereas the front one is pre-set at approximately 1400 g (3.1 lbs).

The safety is positioned at the front end of the trigger guard protruding outward in the direction of the barrel which is somewhat unusual. It comes in a form of a circular knob which blocks the triggers and firing spring.

The barrels are interchangeable between the rifles in the ZH series, meaning that whenever the user decides to change the barrel combination, what they are really doing is not only changing the barrel but rather converting the rifle to another model. In other words, different model numbers are really just there to mark different barrel configurations. Disassembly of the rifle and changing of the barrels is done easily by pressing the small knob on the left side of the action body.
