The Midwest Industries Alpha Fixed Beam Stock is a black synthetic, side-folding AK stock built around a heavy-duty, 4140 heat-treated steel folding mechanism (brand part no. MIALPHAFBSF). Midwest Industries ships it configured for rifle use, though it’s also compatible with a Gear Head Works Tailhook for arm-brace use (cosmetic plug sold separately). An adjustable polymer cheek piece and adjustable buttpad let shooters dial in a proper fit, even over a plate carrier or heavy gear, while the reversible design configures for right- or left-side folding. Requiring a firearm with a 1913 rail adapter, it adds just 8.5 inches to overall length deployed and only 0.75 inches when folded, weighing 1 lb 4 oz total.
