Magpul MOE SL-S Carbine Stock Mil-Spec AR-15 Black
The Magpul MOE SL-S Carbine Stock in Mil-Spec Black is the ultimate evolution of the beloved MOE SL platform, combining a whisper-thin profile with genuine waterproof onboard storage — making it the slimmest storage-capable carbine stock available for AR-15/M4 platforms.
- Dual-side release latches allow ambidextrous, glove-friendly length-of-pull adjustments
- O-ring sealed, 10-meter waterproof battery tubes keep essentials protected in any conditions
- Leaf-spring tension system delivers a rattle-free, solid lock on mil-spec receiver extensions
- Enhanced cheek weld promotes consistent eye alignment and faster target acquisition
- Rolled toe and angled rubber butt-pad optimized for comfortable use over body armor
- Integrated ambidextrous QD sling swivel socket supports quick one-point or two-point sling setups
Who This Is For
The MOE SL-S is purpose-built for AR-15 owners who demand a low-snag, high-performance stock without sacrificing practical storage or sling versatility. It's an ideal upgrade for duty and tactical shooters who wear body armor, competitive 3-Gun athletes who need fast transitions, and everyday range enthusiasts who want a clean, modern stock that still carries extra batteries or small essentials internally. If you've been searching for the thinnest, most refined storage stock on the market, this is it.

Frequently Asked Questions
Will the MOE SL-S fit my mil-spec AR-15 buffer tube?
Yes — the Magpul MOE SL-S is designed exclusively for mil-spec diameter receiver extensions (buffer tubes). It is not compatible with commercial-spec buffer tubes, which have a slightly larger diameter and different taper. If you're unsure which spec your rifle uses, mil-spec tubes are typically found on quality mil-spec AR-15 lowers and have a 1.148" outer diameter. Check your current stock or lower manufacturer's documentation before ordering.
What can I store in the waterproof battery tubes, and how waterproof are they really?
The MOE SL-S features two O-ring sealed storage tubes rated to 10 meters of water resistance, making them genuinely protective against rain, submersion, and field exposure — not just splash-resistant. Each tube is sized to hold standard CR123A batteries, AAA batteries, or similarly sized small survival items. The dual-tube design gives you convenient, fast-access storage without adding meaningful bulk to the stock's slim profile.
How does the MOE SL-S differ from the standard MOE SL stock?
The MOE SL-S ("Storage") builds directly on the MOE SL platform with two key additions: the waterproof onboard storage tubes and a slightly revised leaf-spring tension system that provides a marginally smoother feel during length-of-pull adjustments compared to the original SL. Both stocks share the same slim, low-snag profile, dual-side release latches, enhanced cheek weld, and QD sling socket. If you want all the ergonomic benefits of the SL with added utility, the SL-S is the natural step up.
