Why are Commercial AR Buffer Tubes different than Mil-Spec?

December 2nd, 2008

I recently received a Magpul CTR stock, but it’s for a mil-spec extension tube and not a commercial one. So I’ve decided to pick up a mil-spec tube to avoid this issue in the future.

What’s the purpose of this difference?

As always, Brownell’s HowtobuildanAR15.com has a video on the subject of AR maintenance.
