Go to P2P server
Create a URF room and join red team, your other friend/account at blue team
Do free kills until 160 kills with the weapon you desire like SG
After that go to BD and spam F5 until UDP error appear
Do this over and over again until you reach the mastery you desire
If BD not working, switch and do it again
