series CZ 457 Miniset

The CZ 457 rimfire rifles have many advantages. One of the most important of them is the simple modular design of this series. Every model from this family is an "open system", in which the customer can change such key parameters as the caliber, barrel length and barrel profile.

For this purpose there are minisets, economical sets consisting of a barrel, polymer magazine with the capacity of five rounds of the corresponding caliber (in the case of the magazine for .22 LR cartridges, the set includes a magazine well insert as well) and Allen wrenches necessary for barrel replacement. Safe barrel removal and reassembly can be easily managed by any user, provided that the enclosed illustrative manual is complied with. A simple instruction video is available as well.

The plentiful and continuously extended supply of minisets for the CZ 457 series rimfire rifles allows the customer to unleash their fantasy and build a firearm exactly according to their wishes and needs. The only partial limitation is the cavity for barrel mount – in the case of wooden stocks for thin-walled barrels the cavity must be first widened, best by a gunsmith, before a Varmint barrel can be fitted. Polymer stocks for the Synthetic models are all designed as universal.

Main features CZ 457 Miniset

Anti-corrosion surface treatment

Metal components in the minisets for the CZ 457 series rimfire rifles are provided with high-quality surface treatment with extraordinary mechanical and chemical resistance.

Cold-forged barrel

The barrels for minisets for the CZ 457 series rimfire rifles are made in-house by proven cold-forging, which ensures their constantly high accuracy and long service life.

Easy installation

The removal and installation of barrels of the CZ 457 series rimfire rifles is very simply for the user and requires just the minimum tools, included in this miniset. When converting to another caliber, just the barrel needs to be replaced, and the magazine in some cases (the magazine is identical for the .22 WMR and .17 HMR calibers; a polymer insert is inserted in the magazine well for the .22 LR caliber).

Wide range of barrel profiles

The offer of minisets for the CZ 457 series rimfire rifles includes thin-walled barrels with or without mechanical sights, with the length of 24“ or 28,6“; thick-walled (Varmint) barrels with the length of 16“ or 20“; and a thick-walled striated 20“ barrel.

Choice from three calibers .22 LR, .22 WMR, .17 HMR

The minisets for the CZ 457 series rimfire rifles are available in the proven three calibers of .22 LR, .22 WMR, .17 HMR, which enable a wide range of uses from target or fun shooting to hunting. Varmint barrels with a narrowed Match type chamber for high-accuracy shooting are available for .22 LR cartridges.
