A drop-in replacement buttstock for AR15/M4 mil-spec carbine buffer tubes, the SL-K is designed for compact PDW style weapons or users desiring a small and light stock. Features a short and slim profile, a smaller rubber butt-pad with rolled toe for easy shouldering and sure grip, and a 1.25” 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
