All American Bore Size??

[PartsMart]

Ive got an Smart Parts All American 16 in barrel. And Ive been looking everywhere for the bore size but i cant find it? can u help me, and what paint works best with it?

[Silent Knight]

there are different 3 sizes for this barrel and most barrels out on the market today, small, medium(standard), and large.

ligh grey back - small bore

black back - medium(standard) bore (this barrel was designed to shoot RP Scherer paintballs!)

dark grey back - Large bore

You are talking about the Standard barrels, aren't you?
Well, in that case it is a .689 bore size. I mean something like that, because mine (standard Shocker) is more like .690.
It was Nick Truter from Smart Parts Europe, who told me that, so...
