The Magpul MOE SL-S Carbine Stock (MAG653-GRY) in Gray 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, located on both sides of the stock to enhance cheek weld while maintaining a streamlined footprint. Each tube is O-ring sealed and waterproof, ideal for storing CR123A batteries, AA batteries, or essential small parts for field maintenance.

An internal anti-rattle leaf spring system ensures a tight and secure lockup on the receiver extension, minimizing 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 provide versatile sling configurations for tactical, hunting, and precision rifle builds.

The Gray finish offers a modern, professional appearance that pairs well with two-tone rifle builds and contemporary AR platforms.

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