I'm afraid this comparison doesn't accurately reflect what happens IRL/in an actual game because targets wouldn't just stand there while being shot at. From experience (I have ~12 500 kills with the AC42), it's much harder to use the ac42 on burst mode at this distance (~100 m) if the target is moving, simply because the delay between shots is significant (~75 ms internal burst delay and 225 ms delay between bursts; bullet travel time ~125 ms for 100 m distance) - so even if you lead your shots properly, only a single shot from a burst might actually hit target. Also, it seems that you're shooting at a higher than intended rate with the AC42 in the video - again, it wouldn't have needed a buff if that were the ACTUAL RoF. At this distance, I wouldn't use any gun on burst/full-auto mode; I'd use single-fire instead - the SFAR outclasses the other ARs at range since it requires only 5 bullets to kill, while both the AC42 and M5A3 have a BTK of 6 at this range. I don't think the 150 ms difference in TTK (SFAR, 300 ms vs AC42, 450 ms) in the 30-75 m range is justified.
