Well, in short, listen: M16 is an updated version of M4 (sort of like AK-74 / AK-47). She, if I'm not mistaken, has increased accuracy (due to barrel lengthening) and rate of fire, it seems that bullets are also used with a smaller caliber, which made it possible to increase the clip. In Weiss and San, for example, M4 is used, and in GTA3 - M16.
In general, I really like the Colt-45 - a kind of symbol of the criminal world of drugs. You know, when I walk alone through the dark streets of Portland or Shoreside, I feel much more comfortable having a gun with me :)
In my opinion, one is simplified ... I also don’t distinguish the difference, the main thing is to wet it ... But I don’t like American machine guns ...

and so - FISTS (if with rapid speed - it’s completely deadly weight!) And a shotgun

in 1986 was not IN PRINCIPLE M4, it was put into service, it seems, in 1990. It's just that the developers of Weiss rushed things ... But the M16 was at that time.
By the way, Weiss also has Kalash, but he is not involved - his model does not even have a badge! And in my opinion, he is just one of the "three".
