CZ-USA manufactured this polymer magazine for the CZ 455 American bolt action rimfire rifle, chambered in .17 HMR. The maximum capacity for this magazine is 5 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.
