Absolutely, especially if you're one of the believer in high torque. As the barrel is tightened, the surfaces are pressed against each other harder and harder, and without antiseize they can gall. This is a phenomenon that will make the surfaces stick to each other, and once that happens it won't go any further. You can't finish tightening it, and you'll have a hell of a time trying to unscrew it again. I use copper paste for this, it seems to have the best lubricity of the types I have tried.
