The local I know everything about every . Has stated that a 7.62X39 upper will fit a AR15 5.56 lower, and all you have to have is the 7.62X39 clips to go with the upper. If so I will buy an upper assy. If not I think I'll just take old 60 year old fist and knock this wet behind the ears turd out. Your call. I'm gonna knock hell outta him anyway, he just pisses me off in general.
