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 Tatra Rifle Review

The Brno Tatra rifle is a series of combination rifles and double-barrel shotguns that were also known under the name Tatra. These rifles feature a robust sliding wedge locking mechanism that locks into place when the bascule is closed, providing extra safety. The Brno Tatra is referenced in the literature under various names, such as Brno CZ 584, CZ 584 Kozlice etc. Tatras can use either a classic 12- or 16-gauge shotgun ammunition for both barrels or a combination of 7x65R, 7x57R, .222 Rem., .308 Win., or .30-06 Spr. rifle cartridges and 12/16-gauge shells.

The light weight of 3-3.5 kg makes it a comfortable gun to carry even during long days out on the hunting range. An adjustable trigger also allows for greater precision and accuracy when shooting at longer distances.  The safety is located at the rear of the gun, above the handle. To activate it, you must pull it backwards. The front trigger controls the rifle barrel while the rear one controls the shotgun barrel. Additionally, the front trigger also functions as a hair set trigger.

By pulling the lever on the upper back side of the action to the right, Brno Tatra can be opened and loaded. On the rifle, the barrels are arranged in a typical order, with the upper barrel being used for shotgun rounds and the lower barrel for rifle cartridges. One typical Brno feature preserved on the Tatra is the possibility of changing the barrels within the series, chambering the gun for different configurations. The barrels are soldered together like with most other Brno double barrel firearms.

There are two terms found for similar thing: quick release scope mounts and quick detach scope mounts. Term quick release scope mounts is used mostly in Europe and quick detach scope mounts is used mainly in USA, although they mean the same thing. With these terms we describe a scope mount that can be quickly removed from the rifle in the field without using any tools and quickly attached back on the rifle when needed.

Main advantages:

  • possibility to use multiple scopes on the rifle,
  • easy transportation of the scope and the rifle separately,
  • if scope fails, it is possible to immediately detach it and use iron sights.

FIXED vs DETACHABLE scope mounts

Fixed scope mounts are mounted to the rifle with screws and sometimes even with glue. This means that it is impossible to attach or detach the scope mount using bare hands without using tools. It also means that they are not meant for constantly being attached on or detached off the rifle. Once you screw the mount on the rifle, it normally stays there for a longer period of use.

Detachable scope mounts offer possibility to attach or detach them without using any tools. This is extremely handy while transporting the rifle and the scope separately and it also offers multiple solutions of different optics on the same rifle. Detachable scope mounts can be attached or detached from the rifle in a matter of seconds, using bare hands.

DETACHABLE vs REPEATABLE scope mounts

It is important to know and understand expressions “detachable” and “repeatable” while talking about scope mounts. Term detachable scope mounts implies scope mounts that can be quickly attached or detached without using any tools. However, when you detach this kind of mount and attach it back on the rifle, it is recommended to zero the rifle before using it again. Procedure of detaching and again attaching the mount will probably need a sighting in before next shooting, because mount will not be secured on the rifle in the perfectly same position and conditions as it was before detaching it off the rifle.

On the contrary, repeatable scope mounts are most sophisticated mounts. These scope mounts are also detachable, however – they provide removing scope from the rifle and attaching it back again without zeroing the rifle every time. This means that they are made more precisely and that they are offering a possibility of using different optical sights / scope on the same rifle. These mounts are ideal for hunters who can use optical and iron sights interchangeably, depending on the needs in different situations. With the repeatable scope mounts, it is useful to keep them oiled as well as the upper part of the rifle, so that repeatability is more ensured. With a touch of oil, the repeatability might be better, because parts of the mount will always return to their previous locations.

Different types of repeatable scope mounts:

  • Pivot mounts,
  • Dentler mounts,
  • Picatinny repeatable mounts,
  • 12 mm dovetail repeatable mounts (for break barrel rifles, such as Steyr Duett, Blaser B750, Fair Combi, Fair SLX 800, Bettinsoli rifles, etc.),
  • Original repeatable mounts, made by manufacturers of rifles for their rifles (Blaser mount, Sauer SUM mount, Mauser M03 mount, Steyr Monoblock mount, etc.).

TIP OFF / ROLL OFF vs SLIDE ON mounts

Nowadays, there are a whole lot of different possibilities, made for attaching riflescopes on the rifles. There are also a lot of different expressions, having the same meaning. It is good to know that tip off and roll off mounts are basically the same thing. They represent quick release scope mounts for dovetails and rails which can be rolled or tipped off the rail vertically to the side of the rail. On the contrary, there are also slide on mounts available on the market. They represent quick release scope mounts that can be slided on or off the rail or dovetail from front or rear side of the rail / dovetail. All of these expressions are mainly used for separate rings that can be attached to the rails / dovetails. As far as functioning the rifle, it does not matter which one of these mounts you choose – tip / roll off or slide on mounts. If they are installed correctly, they are all going to work. However, the main difference between them is the principle of attaching them on rails on dovetails.
