Q: What comes in this Magpul MOE SL-K FDE combo kit? A: You get the genuine Magpul MOE SL-K stock in Flat Dark Earth plus a complete carbine buffer tube assembly — the receiver extension (buffer tube), carbine buffer, recoil spring, castle nut, and end plate. It’s everything needed to mount the stock to an AR-15 lower. The only thing you supply is the lower receiver itself.

Q: How is this different from the stock-only listing? A: The standalone Magpul MOE SL-K (MAG626FDE) is the buttstock by itself, with no buffer tube, buffer, spring, castle nut, or end plate. This combo bundles the SL-K with a full carbine buffer tube assembly so you can finish a lower in one purchase instead of ordering parts separately.

Q: What’s the difference between the SL-K and the standard SL? A: The SL-K is the “Kurz” (short) version of the slim-line SL. It has a shorter overall body, so the collapsed and extended length-of-pull are both more compact — about 10.3″ collapsed and 13.6″ extended. That makes it a good match for AR pistol builds, SBRs, CQB setups, or shooters who find standard carbine stocks too long even at the shortest position.

Q: Does the FDE color match other Flat Dark Earth Magpul parts? A: Magpul keeps a consistent FDE across its current polymer line, so this stock pairs well with Magpul FDE grips, handguards, and magazines. Shade can vary slightly between different brands’ “FDE,” but Magpul-to-Magpul FDE parts match closely.

Q: Is the SL-K a good choice for an AR pistol build? A: Yes. Its short length-of-pull and light 7.9 oz weight make it popular on AR pistol and SBR builds where overall length and weight matter. It mounts on a standard mil-spec carbine buffer tube — the same tube included in this combo.

Q: Does this combo work on an 80% lower build, and is it made in the USA? A: It does — the kit installs on any standard AR-15/M4 carbine lower, including 80% lowers you finish at home (you’ll need a castle nut wrench and an armorer’s tool or punch to stake the end plate and torque the castle nut). And yes, the SL-K stock is made in the USA, and the kit ships fast from Daytona Tactical.
