The Magpul MOE SL-S Mil-Spec Carbine Stock (Magpul part no. MAG653-FDE) is a direct replacement buttstock for AR15/M4 carbines built on mil-spec receiver extension tubes, finished in flat dark earth. It’s the storage-capable version of Magpul’s flagship MOE SL stock, adding dual waterproof battery tubes and an O-ring-sealed storage compartment rated to 10 meters while keeping the slimmest profile of any storage-tube stock Magpul makes. A rolled toe and angled rubber butt-pad are shaped for a solid cheek weld and shoulder purchase even while wearing body armor, and an ambidextrous QD sling swivel socket comes built in. Made in the USA, it’s a smart upgrade for shooters who want onboard storage without adding bulk to their carbine.
