Good picture but I need a little more detail.
I have line on a couple of MANN barrels but the collars are gone. Question; with the collar removed how tall is the remaining shoulder? I'm trying to determine the barrel can be succesfully tightened to an action without the collar or will I have to make some sort of bushing to take its place?
