Frequently Asked Questions
Will the MOE SL-S fit my carbine's receiver extension?
The Magpul MOE SL-S is designed exclusively for mil-spec diameter receiver extensions (also called buffer tubes). It is not compatible with commercial-spec tubes, which have a slightly larger and tapered outer diameter. Before purchasing, verify that your AR-15 or M4 carbine uses a mil-spec buffer tube — this is standard on most factory rifles, but commercial-spec tubes are common on some budget builds.
What can I store in the waterproof compartment?
The SL-S storage tube is sized to hold two CR123A lithium batteries, making it a convenient on-rifle power reserve for weapon lights, lasers, or night-vision devices. The compartment is sealed with an O-ring and rated waterproof to 10 meters, keeping your stored items protected from rain, humidity, and submersion during field use.
How does the MOE SL-S differ from the standard MOE SL stock?
The primary difference is the addition of a sealed waterproof storage compartment in the SL-S, which replaces the hollow tube of the standard SL. Both stocks share the same slim silhouette, dual ambidextrous release latches, enhanced cheek weld, and QD sling socket. The SL-S uses a slightly refined leaf-spring tension system that provides a marginally lighter feel on the buffer tube compared to the original SL, while still eliminating stock wobble and rattle.
