and that is why neither of you are in charge of Anti cheat in BF4
He has no dodgy stats and if you are talking about the HS 180's well that'd be the syncing issues since last patch.
Note his two most used guns are both 34 max dmg guns which still give one frame kills due to packets getting sent the same time. Nothing dodgy there what so ever am afraid to say.
Tony you know I want your babies and love you long time but this is the problem with people calling hacks. You don't know enough to make that judgements.
I did a round on TDM Lockers last night with 80% HS ratio using AEK and Magnum only (50% kills with each) at 21-3 and yes many hacks were called. Then to give other people a chance I only used M40 in 48 man TDM and went 16-5 only quick scoping with a 75% HS ratio.
