Magpul MOE SL-S Stock

The sleek profile, dual-side release latches, and waterproof battery tubes make the SL-S  the slimmest storage tube stock available. The SL-S provides a great cheek weld and an o-ring sealed, 10m waterproof storage area that is perfect for storing spare batteries. A rolled toe and angled rubber butt-pad are optimized for use with a chest rig, and an ambidextrous QD sling swivel socket is included. 

A leaf-spring tension system provides a solid fit on mil-spec receiver extensions. The MOE SL-S is one of the best storage stocks available.
