CZ 457 Varmint Barrel Set Features The CZ 457 Varmint Barrel Set brings a 24 inch barrel chambered in .17 HMR built to fit both the CZ 457 and 455 receiver platforms. The Nitride finish adds corrosion resistance and a tough wear surface helping the barrel hold up to repeated handling and exposure in the field. A 1/2x28 threaded muzzle allows shooters to mount a suppressor muzzle brake or other device without additional gunsmithing. The 24 inch length is suited to varmint-style shooting giving the .17 HMR round room to reach its full velocity potential for flat-shooting accuracy on small game. Because it is built to the 457 and 455 platform s factory dimensions the barrel set swaps in without requiring custom fitting making it a straightforward way to add a new caliber option to an existing rifle. This is particularly useful for owners who already have a 457 or 455 action and want to expand into varmint hunting without buying a whole new rifle. The threaded muzzle keeps the barrel versatile for both open shooting and suppressed use. The CZ 457 Varmint Barrel Set is available for sale at GrabAGun for CZ rimfire owners looking to add a dedicated varmint-ready barrel to their setup.
