This variant of CZ's 457 American sports a newly-designed synthetic stock that borrows ergonomics and styling cues from their 557 American Synthetic. That synthetic stock makes the rifle near impervious to the elements. 1/2A-28 threads and their especially tight chamber tolerances make this rifle an ideal suppressor host. Not equipped with sights, this rifle has 11mm dovetails milled directly into the CNCed billet action for the solid mounting of rails or rings. The cold hammer forged barrel, fully adjustable trigger, push-to-fire safety and interchangeable barrel system all add up to equal a rifle that will last generations.
