I made a thread a couple months ago and didn't really get the answer. Will a 5.56 upper receiver work with my 7.62x39 build. Of course I'm going to use x39 barrel,bcg, etc. but is the upper receiver interchangeable??

I'm going to go ahead and treat this as a serious post, because hey, we're all new to AR's at some point. On an AR-15 lower receiver, any AR-15 upper receiver will work. just make sure you use the proper magazines, and if you're going featureless, make sure all of our upper receivers are compliant.
