Magpul | MOE SL-S Carbine Stock | Black

The MOE SL‑S (MAG653) is Magpul's slim MOE SL carbine stock with storage. Two O‑ring‑sealed tubes in the sides hold CR123A or AA batteries (Magpul rates the plugs waterproof to 10 meters) without turning the stock into a fat SOPMOD clone. You still get the SL cheek weld, an angled rubber butt‑pad that works over armor, and a drop‑in fit on a mil‑spec carbine receiver extension. Magpul calls it the slimmest storage stock they make. Made in the USA.
