Description
The Magpul MOE SL Carbine Stock is one of those upgrades that just makes sense. Swap out that rattly factory stock that came on your AR-15 or M4 and you get a slim, lightweight buttstock that snaps into place and stays put. It's a straight drop-in for any Mil-Spec sized carbine receiver extension tube, so if you're running a Colt, Ruger, S&W, SIG, LMT, or a similar setup, you're good to go. Just double-check that you've got a Mil-Spec tube and not a commercial-spec one before ordering.
What Sets the MOE SL Apart
The big story here is the internal anti-rattle system. Older MOE stocks were known to wobble a bit, and Magpul solved it with internal leaf springs instead of adding a second friction lever like the CTR uses. The result is a lock-up that folks compare to a fixed A2 stock, yet it still adjusts smoothly through its length-of-pull range. A premium chrome-silicon lock spring handles the adjustment button and holds up over the long haul.
Built to Move With You
The MOE SL earns its Slim Line name. The sloped cheek weld gives you a wide, comfortable contact surface without adding bulk, and the rolled toe lets you shoulder the rifle fast, even when you've got a plate carrier on. Dual-side release latches sit shielded and anti-snag, so they won't catch on gear or fire off by accident. The angled rubber butt-pad grips your shoulder and soaks up a little recoil, keeping the gun planted during quick strings of fire. It also plays well with Magpul ASAP and ASAP QD receiver-mount sling attachments if you're building out a sling setup.
Everyday Dependability
Made in the USA from Magpul's tough reinforced polymer, this stock is built to take field abuse, rough weather, and thousands of cycles without complaint. Weighing in around 9.6 ounces, it's a practical, no-nonsense pick for a patrol rifle, a lightweight build, or just modernizing a trusted platform.

Frequently Asked Questions
Will the MOE SL Carbine Stock fit my AR-15?
It fits AR-15, M4, and M16 carbines running a Mil-Spec sized receiver extension tube, which covers most rifles from makers like Colt, Ruger, S&W, SIG, and LMT. The one thing to confirm first is whether your buffer tube is Mil-Spec or commercial-spec, since this stock is built for the Mil-Spec size. The receiver extension tube is not included, so you'll reuse the one already on your rifle.
Does the MOE SL wobble on the buffer tube like some other stocks?
No, and that's kind of its whole thing. The internal anti-rattle leaf-spring system gives it a tight, wobble-free lock-up that many users compare to a fixed A2 stock. It manages this without a separate friction lever, so you still get smooth, fast length-of-pull adjustments.
Is the MOE SL Carbine Stock hard to install?
Not at all. It's a true drop-in replacement, so you slide off your old stock and slide the MOE SL onto the same Mil-Spec receiver extension. No gunsmithing or special tools are needed for the swap.
Can I mount a sling to the MOE SL?
Yes. It's compatible with Magpul ASAP and ASAP QD along with other receiver-mount sling attachments, giving you flexibility on how you set up your sling. That makes it easy to pair with the rest of your build.
