The CZ 455 is a versatile and accurate bolt-action rimfire rifle that was designed to eventually replace the CZ 452 series. Chambered in .22 LR, .22 WMR, and .17 HMR, the CZ 455 stands out for its interchangeable barrel system, allowing users to easily switch calibers by changing the barrel, magazine, and adding a mag-well spacer. This rifle features a 21" hammer-forged barrel with a polished and blued finish, and a machined receiver also finished in satin bluing. The American-style walnut stock is well-crafted, with excellent checkering and a seamless plastic buttplate. The rifle includes an adjustable trigger, integral 11mm dovetail for scope mounting, and a polymer 5-round magazine. Despite some noted feeding issues with the magazine, the CZ 455 American is praised for its uncanny accuracy at 50 yards, especially when using CCI Maxi-Mag ammunition. The Ultra Lux, now part of the CZ 455 platform, retains the features of its 452 predecessor, including a 28.6-inch barrel, tangent rear sight for quick elevation adjustments, beech stock with cheekpiece, and a 10-round magazine. Overall, the CZ 455 American, which was discontinued in 2018 and replaced by the CZ 457, remains a top choice for those seeking a high-quality, adaptable rimfire rifle.
