What ever you do stay away from the M4 Deluxe. That was one of the first aeg's that i bought and i had to return it right away. It looks pretty cool however the trigger is plastic and breaks very easily. I bought that at cabelas a year ago (maybe aftermath fixed the problem), brought it home, charged the battery and went outside to test it out. I didn't even squeeze the trigger hard and it just snapped! So my advice is stay away from that gun. I have heard that aftermath put metal triggers in their new guns.
Hope that this helped, if not then just disregard this post.
