Magpul MOE SL-K Carbine Stock for AR-15/M16/M4 - Flat Dark Earth (Mil-Spec Tube Not Included)

The Magpul MOE SL-K carbine stock is a compact, lightweight replacement for AR-15, M16, and M4 platforms that prioritizes maneuverability and comfort in tight spaces. Whether you're building a short-barreled rifle, running a modern tactical carbine, or just prefer a slimmed-down profile, the SL-K delivers the controls and ergonomics that Magpul's known for without the bulk of a full-length stock. It's a drop-in fit for standard mil-spec (1.14" O.D.) buffer tubes, so installation is straightforward on most modern ARs.

What sets the SL-K apart is its thoughtful design for real-world use. The cheekweld has a comfortable slope that won't fight you when you're running optics or irons, and the rubber recoil pad features a rolled toe that makes shouldering faster and plays nicer with body armor if you're wearing it. The ambidextrous latch cycles smoothly in both directions and stays tight without rattle—no extra springs, locks, or levers needed. Built from steel where it counts, the latch won't flex or fail under hard use, and a molded sling loop gives you 1.25" of attachment real estate out of the box.

The stock accepts Magpul ASAP and M-LOK QD Sling Mount options (sold separately) if you want to add pushbutton QD sling swivels to your setup. This is the flat dark earth color variant; note that the mil-spec buffer tube is not included—measure your existing tube before ordering if you're unsure of compatibility. Ideal for anyone running a short-stroker, an SBR, or just building a lighter, more compact AR platform.

Frequently Asked Questions

Will this fit my AR-15?

Yes, the MOE SL-K is designed as a drop-in replacement for any AR-15, M16, or M4 platform that uses a mil-spec (1.14" O.D.) buffer tube. If your rifle currently has an adjustable M4-type stock, the SL-K will install the same way. Note that the buffer tube itself is not included; you'll use your existing tube or source one separately if needed.

What's the difference between the SL-K and other compact stocks?

The SL-K is built around a short, slim profile with a sloped cheekweld and ambidextrous latch that stays tight without rattling. The rubber recoil pad has a rolled toe for faster shouldering and better fit with body armor. The steel latch is built to handle hard use without flexing, and you get a molded sling loop plus compatibility with Magpul's QD sling mounting systems.

Can I add QD sling mounts to the SL-K?

The stock has a built-in 1.25" sling loop, so you can attach a standard sling immediately. If you want pushbutton QD sling swivels, the SL-K accepts Magpul ASAP and M-LOK QD Sling Mount options sold separately.

Is this stock good for short-barreled rifles or SBRs?

Yes. The SL-K is designed for compact, PDW-style weapons and users who want a small, maneuverable profile. It's a popular choice for short-strokers and SBRs where every inch counts and fast handling is a priority.
