Q: What buffer tube spec does the Magpul MOE Stock FDE require?
A: The MOE Stock is designed for mil-spec carbine receiver tubes with a 1.148″ outer diameter. The buffer tube assembly included in this kit is mil-spec, so the stock and tube are a matched fit straight out of the box.

Q: Does the FDE color match other Magpul MOE accessories?
A: Yes. Magpul uses consistent FDE pigment across the MOE product line — stocks, pistol grips, handguards, and magazines. You can build a matched Flat Dark Earth lower using Magpul components without noticeable color variation between parts.

Q: Will this combo work with an 80% lower receiver?
A: Yes, as long as the 80% lower is machined to standard AR-15 mil-spec dimensions. The buffer tube threads in and the stock mounts exactly the same as on any factory lower receiver.

Q: What’s the difference between the MOE Stock and the CTR Stock in FDE?
A: The CTR adds a supplemental friction lock that eliminates wobble between the stock and buffer tube. The MOE Stock uses standard mil-spec tolerances for fit and has a simpler, slightly lighter design. If wobble-free lockup matters to you, go CTR. If you want a clean, no-frills stock, the MOE delivers.

Q: Is the included buffer tube mil-spec or commercial spec?
A: Mil-spec. The receiver extension has a 1.148″ outer diameter. Commercial spec tubes are 1.168″ with a different taper and are not compatible with mil-spec stocks like the MOE.

Q: Does the MOE Stock FDE have a QD sling socket?
A: The MOE Stock has an integrated 1.25″ sling loop but no push-button QD socket. For a rear QD attachment point, replace the included standard end plate with an aftermarket QD end plate.
