The CZ 457 American Combo is the factory barrel-package variant — a single American walnut-stocked rifle shipped with two barrels: one chambered in 22 LR and one in 17 HMR. The combo package demonstrates the 457 platform's interchangeable barrel system at its most practical: two cartridges, two ballistic applications, one action. Buyers who want both calibers save the price of a second rifle while gaining full capability in both. Type: Rifle Action: Bolt-Action Caliber: 22 LR Capacity: 5 Year introduced: 2019, Czech Republic Weight: 99.2 oz Overall length: 38.5" Status: Active Intended use: hunting, varminting, target
