Gunsmithing ARC Nucleus with barloc

On what? The cross bolt, maybe. I don't see the point of putting any on the tenon. Not that doing so would hurt a thing, but why?

Some one feel free to correct me if I'm missing something obvious.
 
I put some little anti-seize on the tenons of my barloc setup. It mainly for the action and barrel. With all the things a rifle can be exposed to at a match, it just a little insurance.
