Q: What buffer tube spec does the Magpul MOE Stock require?
A: The MOE Stock requires a mil-spec carbine receiver tube with a 1.148″ outer diameter. The buffer tube assembly in this kit is mil-spec, so the stock and tube are matched and ready to install.

Q: Does this combo fit a standard AR-15 lower receiver?
A: Yes. The mil-spec buffer tube assembly in this kit threads directly into any standard AR-15/M16 carbine lower receiver. No adapters or modifications needed.

Q: Can I use this on an 80% lower build?
A: As long as your 80% lower is machined to standard AR-15 mil-spec dimensions, this stock and buffer tube assembly installs the same as on any factory lower receiver.

Q: What is the difference between the MOE Stock and the MOE-SL Stock?
A: The MOE-SL (Slim Line) has a narrower profile designed to reduce snag points and save a small amount of weight. The standard MOE Stock is slightly wider with a more traditional carbine stock profile. Both use the same mil-spec tube diameter and have the same fixed length of pull.

Q: Does the MOE Stock Black have a QD sling socket?
A: The standard MOE Stock has an integrated 1.25″ sling loop but no push-button QD socket. If you need a QD point at the rear of the rifle, you can add an aftermarket QD end plate in place of the included standard end plate.

Q: Is the buffer tube in this kit commercial spec or mil-spec?
A: Mil-spec. The receiver extension has a 1.148″ outer diameter. Commercial spec tubes measure 1.168″ and use a different taper — they are not interchangeable with mil-spec stocks like the MOE.
