Best finish for AR SS barrel?

[smschulz]

I have a new SS bead blasted barrel coming for a new build.
What is the best (black) finish for this?
Brownell's Alumahyde ?
Dura-coat?
or others
or would it be better to have it 'blackened' at Robar or somewhere else?

PS... anyone in Houston doing this work?

Lot's of great reports on Dura-Coat...

Ionbond is probably the best.
