OK - Someone a long while ago questioned the use of Garand or M14 rear sights on an Norinco M305. Everyone (almost) knows that this is fine; however, I once added that you could still use the existing Norinco Base, aperture, and spring cover and just swap the elevation pinion and windage knob with USGI. Someone here call BS on this, although he admitted that he had never tried it.
Wow.... I have issues..
.. anyway, after a year or so of procrastinating, I tried it out this morning and Eureka! So, it's official to me at least. If your Norinco rear sight is wonky, you only really need to swap out the elevation pinion and windage knob with USGI. The Norinco base will accept the parts and threading is not an issue.
Funny thing is that the Norinco elevation pinion will not fit the USGI base, (too fat) but who cares....
