CZ 457 Overview
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.
