M16 again might be too long
AK-74 is super short but no battery in the stock, still slipping a tube battery under the dustcover is painless. No M4 mags without a converter though. Rail kits do exist to hang gear on them.
416 is very nice too, but a decent one will be very heavy.
Really the proper airsoft answer is to get them all!
