Product Description


CZ 455/457 American  (Conversion Kit) Miniset 17 HMR 20″ barrel & 5 Rnd magazine

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

We have therefore created minisets for this purpose, which are economical sets consisting of a barrel, polymer magazine with a five-round capacity of the corresponding caliber (in the case of a 22 LR cartridge magazine, the set also includes a magazine well insert) and Allen wrenches that are necessary for barrel replacement. The illustrated, easy-to-follow manual that comes with every miniset ensures the safe removal and reassembly of the barrel by any user. A simple instruction video is available as well.

The extensive, and continuously increased, offer of minisets for the CZ 457 series rimfire rifles allows the customer to unleash their creativity and build a firearm that meets their needs and expectations. The only partial limitation users are faced with is the cavity for mounting the barrel. In the case of rifles with wooden stocks for thin-walled barrels, the cavity must first be widened (we recommend to use a gunsmith), before a Varmint barrel can be installed. The polymer stocks that come with our Synthetic models are designed as universal.

A set for user adjustment of parameters (caliber, barrel length and profile) of the CZ 457 series rimfire rifles. This miniset contains a thin-walled 20“ barrel of the 17 HMR caliber without sights, a polymer magazine for five rounds and wrenches necessary for barrel replacement. The barrel muzzle is fitted with a unified ½“x20 UNF thread with a plug.
