Magpul MOE SL® Hand Guard, Carbine-Length – AR15/M4 - black
Sleek design with improved check-weld, buttock end and two waterproof storage compartments. The (S) is for storage. The SL-S includes a true, O-ring sealed, waterproof storage, and still is the narrowest stock possible to allow a more upright head position with a minimalist footprint. A rolled toe and angled rubber butt-pad are optimized for use with body armor, and an ambidextrous QD sling swivel socket is included. A unique leaf-spring tension system provides a solid fit on mil-spec receiver extensions, with slightly less friction than the original SL.
