Magpul MOE SL-S Stock

Magpul MOE SL-S Carbine Stock — Mil-Spec AR-15 Buttstock with Waterproof Storage

The Magpul MOE SL-S is the pinnacle of AR-15 carbine stock design — a mil-spec direct replacement buttstock that combines the slim, snag-free profile of the flagship MOE SL with the addition of a true waterproof storage compartment. If you've been looking for the slimmest storage tube stock available for your AR-15 or M4 carbine, the MOE SL-S delivers everything you need in the narrowest package possible. Made in the USA.

Slimmest Storage Stock Available — Waterproof Battery Tubes

The MOE SL-S features dual O-ring sealed, 10-meter waterproof battery tubes that keep batteries, fire starters, or other small essentials protected from the elements — engineered into the narrowest profile possible. You get genuine waterproof storage without the bulk that typically comes with storage stocks.

Enhanced Cheek Weld & Upright Head Position

The slim profile allows a more upright head position that promotes a natural, consistent cheek weld across a wide range of shooting positions — particularly valuable for optics-equipped rifles where consistent eye relief is critical.
