To those that have the Galazan BWT gage, from pictures, it looks to me that the bottom brass cone goes in the breech or muzzle to center the barrel and can be raised or lowered to keep this relationship in-line, correct?
Also it seems as if it does not have a ball bearing on the top, but looks as if the thin sheet metal or brass sheet has a spring under it to keep tension on the I.D. of the barrel, and you would then set the indicator stem on the rod and zero it before barrel/s were placed on it! I'm lost on this part.

Also how high are the rods?

Thanks.
