Anyone ever come across this yesterday went to the range with my friend he had a brand new BAR MK111
leupold base leupold rings and a VX111 scope he wanted to sight in on the second shot scope, mounts, and rings ended up on the bench fell off the rifle well seems that the receiver is not drilled and tapped it is drilled and has steel bushings pressed into it which is what you screw the mounting screws into well these bushings popped loose and came right out
