I would love to know if the screw holding the hanger on the 20 gauge barrel goes all the way to the inside. I would not like a pit going 2/3 the way into a barrel at 9-10” from the chamber. And a screw hole is just a big pit which if it goes all the way it is even worse to me. Obviously this was done years ago so some use has occurred without major failure. But today’s infatuation with hyper velocity, high pressure loads would scare me in that mess. Bubba setup for sure.

Why the heck did he not put the spacers where the hanger needed to be and attach to them? That would not have compromised the barrel and done two jobs at once.
