i had a guy in balota rush me in a house i seen the door open so i was prone and down the iron sights .. put a good 10 rounds into him he kept coming he put 3-4 maybe more into me and killed me ... yet the same weapon i could drop zeds with burst from the hip ...would you assume that its desync ... but no yellow or red chain ... i havent managed to have a pristine m4 maybe it makes a difference ... i guess i could rage like a jerk and that should solve the issue ...
