@darkgael... my point about the FF tube is that I believe it is capable of potentially producing more leverage on the rifle as a whole.... not the barrel in particular. I understand that it has less direct contact with the barrel. I'm talking about the principal of the lever.
In a wood stock where the stock material is unstable I'm down with it. But on a tight AR. I don't buy it.
But what works is what works...
