The CZ 457 American SR is a .17 HMR bolt-action rimfire set up from the factory to run a suppressor. Its 24.80" cold hammer-forged barrel is threaded 1/2x28 at the muzzle, so a rimfire can goes on without any gunsmithing, and the full-length tube gets the most out of the cartridge on small game and steel.
A Turkish walnut stock gives the rifle a classic look and a solid hold from the bench or the field, and the receiver's integrated 11mm dovetail takes rimfire rings directly. The detachable 5-round magazine keeps the profile clean under the action, making this a straightforward suppressor-ready rimfire on the proven CZ 457 action.
