AEG is all electric guns. Period.
Consider that a real H&K SL8 is automatic in that it auto loads and readies the next round for trigger pull. Generally an H&K G36 is also classed automatic, though it can auto load and auto fire the round.
I'm not sure there is a distinction between semi-automatic and fully-automatic AEGs.
Consider again that my gas We M&P and my gas We Scar-L are both classed GBB.
My only point is that I suggest you focus on its FPS, and not that it requires individual trigger pulls (I hope I'm correct in this).
