Frequently Asked Questions
Will the MOE SL-S fit my mil-spec AR-15 buffer tube?
Yes. The Magpul MOE SL-S is designed specifically for mil-spec diameter carbine receiver extensions (buffer tubes). It is not compatible with commercial-spec (slightly larger diameter) buffer tubes. If you are unsure of your tube's specification, measure the outer diameter — mil-spec tubes measure approximately 1.148 inches, while commercial tubes measure approximately 1.168 inches. Most factory mil-spec AR-15s and M4-pattern rifles will accept this stock directly with no modifications required.
What can I store in the waterproof storage compartment?
The MOE SL-S features a cylindrical, O-ring sealed storage tube rated waterproof to 10 meters. It is sized to hold CR123A or AA batteries, making it popular with weapon light users. It can also store small survival items, backup fire-starting tools, or other compact essentials. The dual-side release latch system keeps the compartment firmly closed during normal use while still allowing quick access when needed.
How does the MOE SL-S differ from the standard MOE SL stock?
The MOE SL-S (Storage) is the direct evolution of the MOE SL, sharing the same slim profile, dual ambidextrous side-release latches, enhanced cheek weld, and body-armor-friendly butt-pad. The key additions on the SL-S are the sealed waterproof storage compartment and a unique leaf-spring tension system that provides a slightly smoother, lower-friction fit on mil-spec receiver extensions compared to the original SL — resulting in easy adjustment while maintaining a solid, rattle-free lock-up.
