The storage-capable version of the flagship Magpul MOE SL™ carbine stock, the MOE SL-S (Storage) Stock is a direct replacement buttstock for AR15/M4 carbines.

The sleek profile, dual-side release latches, and waterproof battery tubes make it the slimmest storage tube stock available. The SL-S provides an enhanced cheek weld and true, O-ring sealed, 10m waterproof storage area desired by many, but fits it into the narrowest package possible to allow a more upright head position and minimize bulk. A rolled toe and angled rubber butt-pad are optimized for use with body armor, and an ambidextrous QD sling swivel socket is included. A unique leaf-spring tension system provides a solid fit on mil-spec receiver extensions, with slightly less friction than the original SL. The MOE SL-S is the most intuitive, comfortable, and efficient storage stock available.

• Mounts on mil-spec sized carbine receiver extension tube (not included) from manufacturers such as Colt, LMT, Ruger, S&W, SIG, and others (please see the note below)
• Two water-resistant battery storage tubes located on the left and right sides of the stock
  • Each tube will store up to two (2) CR123A lithium or AA batteries
  • Tubes are accessible from the rear in any stock position via hand-removable, o-ringed rubber plugs that are waterproof to 10 meters
• Sloping cheek weld combines a slim profile with user comfort
• Dual-side release latch provides easy adjustment while remaining anti-snag
• Premium chrome-silicon lock spring provides positive locking and long service life
• Internal anti-rattle leaf spring minimizes wobble on receiver extension tube
• Rubber butt-pad offers an anti-slip surface and increases impact protection
• Rollover on the toe allows for easier shoulder transitions and better fit when using body armor
• Compatible with Magpul ASAP®, ASAP® QD, and other receiver-mount sling attachments
• Sling Mounts
  • Rear – Integral push-button QD swivel sling mount accommodates up to 1.5″ swivels (ambidextrous)
  • Rear/Bottom – 1.25″ sling loops

NOTE: There are two basic sizes of M4 Carbine receiver extensions (buffer tubes): mil-spec and commercial-spec. The MOE SL-S will only fit with the common mil-spec tube.
