The Mountain Shadow Steel™, weighing in at just 6 ½ pounds, is a compact, lightweight rifle that packs a heavyweight punch. It features patented Bolt-to-Bore Alignment™ for exact concentricity, and patented No-Fail Cycling™ for guaranteed operation. With its match-grade, hand-lapped, spiral fluted barrel and innovative stock design, you’ll enjoy guaranteed sub .25” 3-shot groups with AllTerra’s custom ammunition and sub .5” 3-shot groups with premium factory ammo.

Design, research and testing of the Mountain Shadow spanned nearly five years, with valuable input from more than fifty hard-core sheep hunters and guides who know what they need from a lightweight, long-range rifle. During that time we developed custom loads specifically for this rifle that produce velocities from a 22″ barrel that exceed the performance of popular loads in a 26″ barrel.
