The CZ 455 is a repeating bolt-action, magazine-fed, rimfire rifle manufactured by the Czech firearms manufacturer Česká Zbrojovka Uherský Brod (abbreviated "CZ-UB") (English: Czech Weapons Factory - Uherský Brod)and imported into the United States by CZ-USA. All CZ 455s have hammer forged, hand-lapped steel barrels, a trigger that is adjustable for weight of pull, and the capability to interchange barrels in different calibers and contours. Calibers available (with rifling twist) are 22 LR (16"), .22 WMR (16") .17 HMR (9"). The CZ 455 is produced with new manufacturing technology capable of closer tolerances for improved accuracy and smoother operation.
Instead of the barrel being threaded into the receiver, as found on the CZ 452, all CZ 455 models use twin set-screws to fix the barrel in the frame as part of an interchangeable barrel system. Additionally, actions can be swapped into any 455 stock without modifications. All versions feature a milled 11 mm dovetail rail atop the receiver for the mounting of optical or telescopic sights.
First introduced in 2010, the CZ 455 was designed to replace the CZ 452 series which is being phased out of current production. 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] Zbrojovka), designer (Josef Koucký) and Malorážka - for rimfire rifle). The Model 1 or ZKM-451 was developed on the request of the occupying German authority in 1943-44, when a very few rifles were built as fully stocked Mauser 98k-type trainers. The receivers of these early .22 training rifles were marked tgf (Tschechische Gewehr Fabrik - German for Czech Rifle Factory) by the German Heereswaffenamt. Because of wartime requirements for combat weapons, assembly and production was halted on all .22 training rifles, leaving a large stockpile of parts and receivers at war's end. After the war, these parts (some of which still have the tgf code) were used along with new barrels and stocks to make the Model 1.
The CZ 455 Standard rimfire rifle corresponds in its construction to the CZ 455 Lux model, but comes with a beechwood stock without a cheekpiece.
The 455 LUX has a lacquered stock made from Turkish walnut featuring checkering located on the pistol grip, and is primarily designed for use with open sights. The steel barrel is fitted with fully adjustable open sights. Barrel length is 20.67 inches (525 mm), weight is 6.17 lbs. (2,8 kg) unloaded.
