i got a mac90 in the 7.62x39 and the last time i shot it i was camping in northern wisconsin and there was a boulder across the lake about 4' round maybe 3-400 yards away. had a 30rd clip full and emptied it at this rock. every round hit the rock which i thought wasnt bad for shooting with open site!! my buddies were aslo amazed! also shoot a few cans a about 100yrd. so i guess they aint so bad. in sure if u get the right bullets & a scope and maybe a mulles brakethey would be very accurate!
