CZ 455/457 American .22 WMR 24" Nitride Barrel

The CZ 455/457 American .22 WMR 24" Nitride Barrel is a direct replacement barrel for shooters and hunters looking to refresh or reconfigure their CZ rimfire rifle platform. Built to CZ's exacting standards, this 24-inch nitride-finished barrel pairs the inherent accuracy of the 455/457 action with .22 Winchester Magnum Rimfire ballistics—a proven small-game and varmint round that delivers more punch than standard .22 LR while maintaining manageable recoil and shot-to-shot consistency. Whether you're switching calibers, upgrading wear, or building a dedicated hunting configuration, this barrel drops into your existing CZ platform without requiring gunsmithing.

The nitride finish delivers real-world durability. This robust surface treatment resists corrosion and wear far better than bare steel, making it ideal for field use in variable conditions—critical whether you're hunting from a blind, working predators over open country, or running rimfire benchrest. CZ's American line reputation rests on no-nonsense design: this barrel is manufactured to the same tolerances as the factory rifles, so you're not compromising on precision or reliability when you choose it as a replacement or upgrade.

At 24 inches, this barrel strikes a balance between velocity, handling, and sight radius. It's long enough to wring out consistent .22 WMR performance without burdening you in the field, and the standard 455/457 tendering means installation is straightforward for anyone comfortable with basic rifle work. Rimfire purists and practical hunters alike appreciate CZ's no-frills approach—function over flash, every time.

Frequently Asked Questions

Will this barrel fit my CZ 455 or 457 American rifle?

Yes. This barrel is manufactured as a direct replacement for CZ 455/457 American platform rifles. Confirm your action generation before ordering if you own an older variant model, but standard 455 and 457 American actions accept this barrel.

What's the advantage of .22 WMR over standard .22 LR?

The .22 Winchester Magnum Rimfire cartridge delivers significantly higher velocity and energy than .22 LR, making it more effective for small-game hunting and varmint work. It also provides flatter trajectory and better penetration on tougher targets, all while maintaining the mild recoil and low cost-per-round rimfire shooters value.

Is the nitride finish factory-applied?

Yes. The nitride finish is applied during manufacturing by CZ USA and comes ready to install—no additional finishing or polishing is required.

Do I need a gunsmith to install this barrel?

CZ 455/457 barrels are user-installable with basic tools and familiarity with rifle takedown. That said, if you're uncertain about removal and headspacing, a qualified gunsmith will ensure proper installation and function.
