BRNO ZKK 601

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 ZKK 601 Rifle Review

Brno ZKK is a series of Czech bolt-action rifles designed and introduced in the early 1960s as a replacement for the vz. 52 rifles. There are three models available in the series, namely ZKK 600, ZKK 601 and ZKK 602, each with a different action length and chambered for a different caliber group. The three models also have somewhat differently shaped stocks; however, apart from those differences, they are structurally the same.

Brno ZKK 601 is the short-action version of the three models. The rifle comes with a Mauser-style breech system with a long claw extractor and an internal box magazine that can hold up to five cartridges. The controlled-feed action system is made of high-grade steel and features a bolt with three locking lugs: two larger, main lugs at the bolt head and a third, smaller safety lug underneath the bolt handle which acts as a backup, providing further safety when the bolt locks into the receiver. There is a two-position safety lever located at the rear right side of the receiver behind the bolt handle which locks the trigger mechanism and blocks the bolt in a closed position at the same time. Additionally, the protrusion on the rear part of the striker from the bolt shroud also indicates when the rifle is cocked, and the striker is activated. Both standard and single-set triggers are available. Users can manually adjust the weight of the trigger pull by turning the screw accessible through the upper side of the receiver when the bolt is removed.

The front sight is mounted on the ramp and secured in place by a spring-loaded catch allowing for easy and fast removal. The rear sight which is adjustable for windage is attached to the dovetail and secured by indentation. Brno ZKK 601 comes with 19 mm milled dovetail grooves at the top of the receiver which are suitable for installing scope mounts.
