My Mini14 is a 1976 200th year of liberty gun, and it will consistenly shoot 2-10" groups at 100 yards

If you consider that consistent
My cousin has the same gun as well, his is the same way. Might have been a '76 thing, but I doubt that since one of my buddies bought a brand new one 2 years ago and its not consistent enough to kill jackrabbits out to 100 yards with a Nikon scope on it.
