don't forget which side is communist. and besides the M4 Is better than the M16 anyway. in my opinion. I'm about to drop a wisdom bomb on your ass. AK-47 is an amazing weapon. it does high damage while having a decent mag size of 30 rounds. however, the iron sights are strange and it is inaccurate as f**k. the M4 also has a 30 round mag while being more accurate and has better iron sights. it doesn't do as much damage but will still knock someone on their ass in one well-placed shot.
M4s take 5.56×45mm NATO while the AK takes 7.62 x 39mm both great choices for ammo. both guns have their pros and cons. so shut up if you don't know what you're talking about. (but I do like the AK-47 more than the M4 only because the AK is better looking.)
