Outer barrel inner diameter

Hi,

I'm looking for the standard inner diameter of an outer barrel (or outer diameter of an inner barrel).

Unforturnately I don't have any accurate tools on hand to get it myself

Why? I'm thinking of trying to zero my red dot as well as to adjust correctly my hopup using a boresight, and I must know what is the closest diameter for this. It may be overkill, but a decent boresight isn't that expensive and could most likely help achive this goal.

Thanks for your help!
