The Magpul MOE SL-S Carbine Stock (MAG653-FDE) in Flat Dark Earth (FDE) is a premium collapsible Mil-Spec stock designed as a direct upgrade for AR15, M4, and M16 carbines utilizing a Mil-Spec receiver extension (buffer tube). The SL-S (Storage Lightweight – Storage) combines a slim, modern profile with enhanced cheek weld and integrated waterproof storage for duty, defensive, and field rifle applications.

The defining feature of the SL-S is its dual waterproof battery storage tubes, positioned on both sides of the stock to improve cheek weld while maintaining a streamlined footprint. Each tube is O-ring sealed and capable of storing CR123A batteries, AA batteries, or small essential parts for field maintenance.

An internal anti-rattle leaf spring system provides a tight, secure lockup on the receiver extension, reducing movement and noise during operation. The reinforced dual-side release latch allows fast, ambidextrous length-of-pull adjustments while remaining protected from accidental activation.

The angled rubber butt-pad with rollover toe is optimized for use with body armor and rapid shoulder transitions, while the integrated ambidextrous QD sling mount and additional sling loops support flexible sling configurations for tactical, hunting, and precision rifle builds.

The Flat Dark Earth (FDE) finish pairs perfectly with modern FDE rifle furniture and optics, making it ideal for cohesive tactical builds and field rifles.

IMPORTANT: This stock is designed specifically for Mil-Spec diameter carbine receiver extensions and will not fit commercial-spec buffer tubes.
