Well I took the base off and there were metal lips at the top of the holes from being drilled and tapped. Also 3 out of 6 screws stripped. So probably my problem. I took some sand paper and knocked the lips off to flush with the barrel. My buddy is a machinist so do y'all think I should have him re drill and tap so I can use heavier duty bolts? And if so what size do y'all think?
