M4A4 or M4A1-S

m4a1-s since it has less recoil and its easier to control and get headshots with.

M4A4 the 30 bullets and spray. M4a1-s if you only double taps

i prefer M4A1-S is better then M4A1

m4a4 cause of 30 instead of 20 bullets better spray options

Definitely the M4A1-S for me because I can't spray for shit. I don't have to worry about recoil near as much.

any other ways to get unlimited bullets

M4A1-S better fire rate, more damage.

M4a1 it's way better, although the m4a1-s is silenced.

m4a4 because it has nearly the same recoil as a ak

to me they are pretty much equal, it all depends on the situation and how you play
