I forgot about the M4a4, maybe because there is no real choice. Dont bother with it. The A1 is far better, it doesnt mark you on the radar. 20 bullets is enough, it does similar damage and I think more accurate; cheaper is a nice bonus
I prefer the M4A4 by miles, more bullets and I prefer the recoil.
20 bullets is not enough for something like a 3v1 or for pre-firing at a corner to delay people. There is so many times that I've been killing people only to die with the M4A1-S because I have to reload. There is a choice and its mostly preference
