I've never owned a TM M4, but as mentioned most stock guns shoot similar ranges.

I'd say under 80 feet you should be able to get a kill with one shot. Around 120 feet it's about a 50/50 chance per shot (so a decent burst should score a hit). After 140... well good luck unless you really like to burn a lot of rounds which is silly. And we're talking about hitting a man sized target with an absence of wind.
