A member of TOS recently took it upon himself to discover what steel Armalite was using in their barrels. He damn near got himself banned from there for doing it, but ultimately the lackey that represents Armalite on the forums went and found somebody that actually knows and shared the information. If you look at the current Chart you'll see that they have a different spec in their column, but it's still a spec nonetheless, and the only reason the information is there is because someone hounded them and got the answer.
