The CZ 452 first appeared in 1954 as the Model 2 (ZKM 452), and was a refinement of the CZ Model 1 (ZKM-451) .22-calibre rimfire bolt-action training rifle that first appeared in 1947. ZKM is an acronym for Zbrojovka-Koucký-Malorážka, the rifle's manufacturer ([Česká] Z brojovka), designer (Josef K oucký) and M alorážka - for rimfire ...
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
Following the success of the .17 HMR, the .17 Hornady Mach 2 was introduced in early 2004. The .17 HM2 is based on the .22 LR (slightly shorter in case length) case necked down to .17 caliber using the same bullet as the HMR but at a velocity of approximately 2,100 feet per second (640 m/s) in the 17-grain (1.1 g) polymer tip loading.
The CZ 457 was designed to improve on the popular CZ 455 rifle family, notably the inclusion of a push-to-fire safety in line with the barrel, and replacement of the 455 stamped steel unitary bottom. Bolt rotation was also reduced to 60° from 90° in the 455.
The rifle's design is based around the Norinco JW-9/15 series of rifles, a simplified Chinese copy of the Czech.22 LR Brno Model 2 (later CZ 452) rifle [5]. The receiver is made from both milled and forged steel while the barrel has a heavy blued finish.

The W8 and W11 had either a fixed rear sight, or a rear sight adjustable only for windage, while the W9 and W12 featured a rear sight fully adjustable for both ...
Another feature of this pistol is the use of polygonal rifling in the barrel bore. This replaces the traditional lands and grooves rifling design with a rounded, smooth polygonal pattern which has a more "hills and valleys" appearance. The CZ 83 was set to discontinued/limited production status by CZ USA in 2012. [1]
