this is not the street name for AK47. it is the street name for an AR15. the ak 47 fires 762x39mm, the soviet m43 round. there were rare versions of the ak47 that fire the 223 round, but these were rare and not numerous enough to consider. the ar15 fires the 5.56 nato, which is the same as 223 remington, 223 for short.
i went and grabbed my 223 full of ss109's
