What are the differences between the 2. Is one higher than the other?

I don't think there is a difference, I always thought A3 is burst while A4 is auto, so the difference isn't related to the upper receiver.

They are the same.... all flat tops. Some manufacturers refer to a flat-top as "A3" some refer to it as "A4" There is a real designation there, but most vendors use that stuff loosely when referring to upper receivers.

A3 = civilian name for flattop receiver
A4 = military name for flatop receiver Usually the same thing when compared side by side, although throughout the years some manufacturers have had problems keeping them in spec - RRA with rail width and DPMS with rail height come to mind. Those problems have long since been fixed, as far as I know, although there may still be out of spec items still floating around out there somewhere. Added link: A1, A2, A3, A4, etc. |

I think I notice manufacturers/distributors using this:
A3's describing flat tops with a carry handle A4's as flat tops without a carry handle |
