Configuration
The free-floating barrel of the CZ 457 Varmint MTR (. 22 LR, .17 HMR and. 22 WMR) is made of steel by cold
hammer forging. The CZ 457 is a replacement barrel rifle, so you can change the calibers easily, by changing
barrel and magazine. Selectable calibers are. 22 LR, .22 WMR and. 17 HMR. The end of the barrel is fitted with
a ½ x20 fixing thread for silencer.
The frame of the weapon is machined from a single piece of steel. The weapon has a redesigned receiver and bolt.
The previous 90 degree turning angle of the bolt handle has been reduced to 60 degrees. This makes opening the bolt
smooth with weapon which has a scope attached.

a roughening on a gripping surface. The stock has a durable pilar bedding and recoil stop made of a steel. The butt plate
of the gun is made of black rubber.

from 800 to 1 500 grams (8 – 15 N). The trigger movement is also adjustable between 0.5 and 7 mm. The weapon's
safety has been redesigned and works now, as well as in most of the rifles of the various manufacturers, i.e.

and thus, of course, a heavier barrel. When shooting CZ 457 Varmint MTR rifle cal. 22LR, CZ guarantees 15 mm bullet
grouping at the distance of 50 m!

The Czech Arms Factory Česka Zbrojovka (Čzub) was founded on June 27, 1936. The factory was founded by Karel Bubla and Alois
Tomiske. In 1938, Germany occupied Czechoslovakia and set up the CZ factory to manufacture mainly Mauser model 98 rifles for
German army. After the Second World War, Czechoslovakia remained in the Soviet sphere and produced weapons for the Soviet Union
as well as its national authorities. During the Cold War, CZ produced, among others, vz. 58-assault rifles and vz. 61 Skorpion
submachine guns. CZ 75 pistols, ZKK 600 rifles, and Skorpion submachine guns have been among the most famous of these products.
Today, CZ is a valued European weapon manufacturer. In 2017, the CZ factory produced almost 300 000 firearms, of which more
than 80% went to foreign exports, to more than 100 countries.
In recent years, CZ has strongly modernized its production plant and introduced a new generation weapon models, manufacturing
pistols, miniature rifles and hunting rifles. The factory currently employs about 1 900 employees.
