I never did slug mine.

I can give it a go in the morning as well as ginning up some other dimensions. I believe (but will look) the front and rear sight bases are sweated to the barrel. Mine had a loose ring on it but right now I don't recall what it was for...handguard retainer maybe? The rear end of the barrel (which you would cut off anyway) is a D shape and referred to as the Knox Form (or sometimes Nox Form). Otherwise, the barrel is round and pretty much a straight taper.
