CZ 457 Varmint .22WMR 20" Nitride Barrel Set

The CZ 457 Varmint .22WMR 20" Nitride Barrel Set is a purpose-built replacement barrel for shooters who want to upgrade or swap calibers on their CZ 457 platform rifle. Built by CZ USA, this barrel combines the flat-shooting characteristics of .22 Winchester Magnum Rimfire with a nitride-hardened finish, giving you a durable, accurate component for varmint hunting, target practice, or precision rimfire competition. The 20-inch length balances velocity and handling, and the nitride treatment resists corrosion and wear, making it a smart choice for shooters who demand longevity and reliability from their rimfire setup.

CZ 457 owners know their rifle as a genuine accuracy platform, and this barrel set lets you customize your gun to match your mission. Whether you're stepping up from standard .22 Long Rifle, hunting prairie dogs at distance, or testing your skills on small targets, the .22WMR chambering offers more punch and flatter trajectory than rimfire standards. The nitride finish means less maintenance headache and more time behind the trigger.

Installation should be performed by a qualified gunsmith or armorer familiar with CZ 457 barrel changes. This is a barrel set only—it does not include a complete rifle or other components—so verify compatibility with your specific CZ 457 action before ordering.
