i am an ar fan. my ex father in law had an ak and said it was far superior. we went to the range and at 100 yrds, the results disagreed with his statement by a good 5 inches. is this the norm or did he just have a bad apple. he was grouping about 6-7 inches through a 3x9 scope, while my bushy was grouping about 1-2 inches. he was not happy and blamed it on ammo even though i was shooting cheap gunshow reloads. are ar15 rifles just more accurate out of the box or is there more to it than that?
