CZ-USA manufactured this polymer magazine for the CZ 455 American & CZ 512 bolt action rimfire rifles, chambered in .22 WMR. The maximum capacity for this magazine is 10 rounds.
CZ products are imported exclusively by CZ-USA, a wholly owned subsidiary of the parent company, Ceska Zbrojovka a.s. Uhersky Brod, (CZUB) of Czech Republic. CZ firearms have been available through normal channels in the US since 1991, through such importers/distributors as Bauska, Action Arms and Magnum Research.
The CZ 455 is the latest generation of the CZ bolt action rimfire. The 455 model will eventually consolidate all of the receivers currently used in the 452 line into one common platform.
The CZ 512 is an entirely new semi-auto rimfire rifle from CZ. The modular design is easily maintained, requiring only a coin as a tool for field stripping. The action of the 512 is composed of an aluminum alloy upper receiver that secures the barrel and bolt assembly and a fiberglass-reinforced polymer lower half that houses the trigger mechanism and detachable magazine.
