Magpul MOE SL-K Carbine Stock Mil-Spec-Gray (M-LOK)


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*.


Made in U.S.A.



  • Mounts on mil-spec sized carbine receiver extension tube (not included) from manufacturers such as Colt, LMT, Ruger, S&W, SIG, and others

  • Dual-side release latch provides easy adjustment while remaining anti-snag
