.22 [Brno] Mod452 Stainless Synthetic

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  chambered for the .22 LR (1:16" twist rate),.

The CZ 452 is produced with new manufacturing technology capable of closer tolerances for improved accuracy and smoother operation. All CZ 452s have hammer-forged, hand-lapped steel barrels, a trigger that is adjustable for weight of pull.

 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 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.
