    ZERO, ZIP, NUNADA, TWO PEAS IN A POD. the difference is in the rate of twist in the barrels, most commercial 223's are 1 in 12" or 14"(I.E. good for bullets up to 55 gr.) Military figured they needed 62gr. (I.E. you need a twist rate of 1 in 7" to 1 in 10") Up to 200 yds. you would not notice a difference. but 300yds or more, makes a BIG change.
