As I posted earlier, it was not uncommon for factory fitted 16 gauge barrels to be a terrible fit. Of course, at some point, Skeuse subcontracted these jobs. Maybe they always subcontracted gunsmithing, I don't know. I talked to the fellow who consigned a poorly fitted 16/20 set to a shop where I was employed. According to him, he may still own the gun. It was cheap and I still couldn't get interested.
