size of a unstamped ultralite?

[Robin N]

hi guy and girls.

i was just wondering if any of you knew the size of a unstamped dye ultralite barrel. iv read that it .688 and this is what i was told, but i have also read that is could be anything from a .689+.

my back is AC threaded if this helps.
i just want to know so that im not buying the same size twice.

thanks

I think it's .688 but I'm sure I'll be corrected if I'm wrong!
