Scope Mounts for Brno ZKM 611

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 ZKM 611 Rifle Review

Brno ZKM 611 is a semi-automatic rifle with a blowback operation presented in 1995. It is based on a design of two brothers – Josef Koucký and František Koucký who worked as engineers for Zbrojovka Brno in the 60s. The rifle was followed by the ZKM 617, chambered for .17 HMR and model 622, chambered for .22 LR. Apart from being chambered for different caliber groups, the mechanical parts and overall design of these models are the same. The production of the ZKM series was taken over by the Zbrojovka Holice after the bankruptcy of Zborjovka Brno between 2004-2006. All the parts left in the factory were bought off for production by the Zbrojovka Holice which marked the series under the KMS acronym.

The rifle comes with a spring-loaded box magazine with a capacity of six or ten rounds. On the front end of the trigger guard is a lever that releases the magazine when pulled. The front sight which is mounted at the front of the barrel is height adjustable, fixed in place with a screw and protected by the guard.

The rear sight is windage adjustable and supplied with a notch. Positioned at the front of the trigger guard is a safety which blocks the trigger. It comes in a form of a small circular push button. The takedown system allows for the rifle to be easily disassembled. This can be done by releasing the connecting screw at the left-hand side of the system. The top of the receiver is grooved for scope mounts installation.
