Mi Alpha Series Fixed Beam Stock - Premium Adjustable Tactical Support

The Midwest Industries Alpha Series Fixed Beam Stock delivers adjustable, dependable support for shooters building or upgrading tactical rifles. This premium stock combines a rigid fixed design with user-friendly adjustability—a cheek piece and butt pad both tune to your body, your optic height, and your loadout. Whether you're running a plate carrier, heavy gear, or shooting from a bench, the curved top surface lets you dial in a consistent, comfortable cheek weld. Built in the USA from high-strength polymer, aluminum, and steel, it's engineered for serious use without compromise.

Two versions give you flexibility: the fixed Picatinny-rail version for rifle applications, or the side-folder model with a heavy-duty 4140 heat-treated steel folding mechanism for compact transport and storage. The side-folder collapses to just 0.75" of additional length, while the fixed version adds a full 8.0". Both configurations are reversible, so left-handed and right-handed shooters get the same solid performance. The steel clamp grips your 1913 rail with large surface engagement and locks up tight in every position.

Three QD sling attachment points give you versatile carry and transition options. The full-length locking lug maximizes structural rigidity, and everything is made to last—Midwest stands behind the Alpha Series with a lifetime warranty. If you're upgrading an AR or compatible platform rifle, this is a stock that works as hard as you do.
