The CZ 455 is a series of magazine-fed bolt-action rimfire repeating 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. It is a successor of the highly popular CZ 452 rifles, and is chambered for the .22 LR (1:16" twist rate), .22 WMR (1:16" twist) and .17 HMR (1:9" twist) calibers. Most versions of the 455 rifle series were discontinued in 2018 and replaced by the CZ 457.^{[citation needed]}

The CZ 455 is produced with new manufacturing technology capable of closer tolerances for improved accuracy and smoother operation.^[1] 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 contours and calibers by simply removing two set screws from the receiver.

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.^[2] Additionally, actions can be swapped into any 455 stock without modifications.^[2] 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.^[2] 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).^[3][4]
