Gents,

What is the correct basic diameter of a regular locking shoulder (before grinding the clearance and bolt pads). One of the prints I found indicated the receiver hole specs at 0.299" . My kit's locking shoulder measures about 0.297". Do I have an undersize locking shoulder?

The 297 is the normal size. the 299 is .002 over for a loose fitting shoulder.
