After looking at the vids, yea the ACR with iron sights at that kind of range didnt hit much because most of the time it wasnt on target. Especially when rocking with it full auto. Already posted a few times that the ACR had a little sway added because it was way too accurate. If people remember before the game kept crashing. At the time I narrowed it down to a bad ACR model and kept asking people to not use it until I could get it fixed. Many refused to listen because they liked the overpowered gun. So the crashes continued.
A statement of fact is that every single bullet gun in the game fires exactly the same. From snipers to pistols. The differences are in ADS zoom, sway, min/max damage, damage falloff, centering speed after each shot, armor piercing and things like that. The game itself doesnt know the difference between a pistol bullet or a .50 round. when deciding hits. All weapons will shoot to the maximum the game will accept but it doesnt mean you will hit anything.
