Magpul MOE SL-K Mil-Spec AR-15/M4 Rifle Stock - Black - The Magpul MOE SL-K Mil-Spec is a drop-in replacement buttstock for AR-15/M4 Mil-Spec carbine buffer tubes, designed for compact PDW style weapons or users desiring a small and light stock. It features a shorter and slimmer profile, a smaller rubber butt-pad with rolled toe for easy shouldering and sure grip, and a 1.25in footman's loop with the ability to accept an optional M-LOK QD Sling Mount for push-button style QD sling swivels. A new, unique, ambidextrous release latch minimizes rattle on the receiver extension without requiring additional locks, levers, or springs (performance dependent on the host receiver extension's dimensional tolerances).
