The CZ 457 American in .17 HMR (brand part no. 02315) pairs a fast, flat-shooting rimfire cartridge with the smooth, reliable action CZ-USA is known for. A durable nitride finish protects the 20.5-inch threaded barrel from rust and wear, and a 60-degree bolt rotation makes cycling quick without bumping a mounted scope’s low ring clearance. The rifle’s integrated 11mm dovetail keeps optics mounting simple, and a 5-round detachable magazine keeps the action fed for range sessions or an afternoon of squirrel hunting. .17 HMR delivers a notably flat trajectory for a rimfire cartridge, making it a favorite for shooters who want precision without centerfire cost.
