CZ 457 MTR SR Set .22LR 20" Nitride Barrel

The CZ 457 MTR SR barrel set in .22LR gives your rimfire platform a clean, modern upgrade path. This is a direct-fit barrel assembly for the CZ 457 MTR chassis system—the kind of focused upgrade that lets you rebuild or refresh your rifle without starting from scratch. The 20-inch nitride-finished barrel combines proven .22LR accuracy with a tough surface treatment designed to handle field use, cleaning routines, and the occasional ding. Whether you're setting up a new build, replacing a worn barrel, or experimenting with different configurations on the same receiver, this barrel set keeps your workflow straightforward.

CZ's MTR platform has earned respect among precision .22 shooters and trainers who value reliable, affordable practice and small-game hunting. The 20-inch length hits a practical balance—manageable in the field, responsive on the bench, and configured for the SR (short rail) variant of the MTR chassis. The nitride coating handles moisture and corrosion better than bare steel, which matters if your rifle spends time in a pack or vehicle.

This is a barrel set, so it's ready to install into a compatible CZ 457 MTR SR receiver. If you're already running the platform or planning to build one, having a purpose-made replacement or second barrel available means you can keep training, zeroing, or hunting without downtime. For serious .22 discipline shooters, benchrest competitors, or anyone who shoots enough rimfire to wear out barrels, a dedicated spare barrel is practical insurance.
