M-16 guaranteed MOA is....
4 MOA or better. How crappy is that? Just got done watching GI Factory on the Military Channel and they showed the production of the M-16. When it was completed they test fired them and if it was under 4 inches at 100 yards, then it was good to go. I can't believe that their standards are that low. When they were checking runout on the barrel, .003" was acceptable.
