Magpul MOE SL-S Carbine Stock Flat Dark Earth

The Magpul MOE SL-S (Storage) carbine stock is a direct replacement buttstock designed for AR-15/M4 platforms with mil-spec receiver extensions. Its slim profile houses O-ring sealed, waterproof storage tubes rated to 10 meters while maintaining a compact, upright cheek weld. The stock features dual-side release latches, an ambidextrous QD sling swivel socket, and an armor-friendly rolled toe with angled rubber butt-pad. A leaf-spring tension system provides a solid fit on mil-spec tubes with slightly reduced friction compared to the original SL.
