The Magpul MOE SL-K Carbine Stock in Gray is a purpose-built, compact buttstock engineered for AR-15 and M4 platforms running mil-spec carbine buffer tubes — delivering a slim, lightweight profile without sacrificing function or durability.

  • Drop-in fit for all AR-15/M4 mil-spec carbine buffer tubes
  • Short, slim PDW-style profile reduces overall weapon length significantly
  • Sloping cheekweld balances low-profile design with positive face contact
  • Rollover toe eases shouldering over body armor or plate carriers
  • Ambidextrous dual-side release latch locks tight and minimizes stock rattle
  • 1.25" footman's loop accepts optional M-LOK QD Sling Mount for push-button swivels

Who This Is For

The MOE SL-K is ideal for shooters building or upgrading a compact PDW-style AR-15, home defense carbine, or duty weapon where a short length-of-pull and reduced overall size are priorities. It's also an excellent choice for smaller-framed shooters, those who regularly wear body armor or plate carriers, and anyone wanting a rattle-free stock with ambidextrous controls — all backed by Magpul's American-made quality.

Frequently Asked Questions

Will the MOE SL-K fit my existing AR-15 buffer tube?

Yes — the Magpul MOE SL-K is a direct drop-in replacement designed specifically for standard mil-spec carbine buffer tubes found on the vast majority of AR-15 and M4-pattern rifles. It is not compatible with commercial-spec (larger diameter) buffer tubes. If you're unsure which spec your rifle uses, mil-spec tubes have a slightly smaller outer diameter and are the more common standard on quality-built AR-15 platforms.

What sling setups are compatible with the SL-K stock?

The SL-K features a 1.25" footman's loop molded into the stock, which accommodates most standard sling hardware including single-point and two-point slings. For push-button QD sling swivels, Magpul offers an optional M-LOK QD Sling Mount (sold separately) that attaches directly to the stock's integrated M-LOK slot, giving you a secure and low-profile QD attachment point without adding bulk.

How does the SL-K differ from the standard Magpul MOE SL stock?

The MOE SL-K is the compact version of Magpul's SL-series stocks, offering a shorter length-of-pull optimized for PDW-style builds, body-armor use, and close-quarters applications. While both stocks share the slim profile and ambidextrous dual-side latch design, the SL-K is noticeably shorter and lighter, making it the better choice when minimizing overall rifle length is the primary goal. If you prefer a more traditional carbine length-of-pull, the standard MOE SL may be a better fit.
