457 AMERICAN SUPPRESSOR-READY 22 WMR BOLT ACTION RIFLE This variant of our 457 American sports a newly-designed synthetic stock that borrows ergonomics and styling cues from our 557 American Synthetic. That synthetic stock, paired with the 457's nitride finish, makes the rifle near impervious to the elements. 1/2A-28 threads and our 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.
