I was playing a private SnD match with some friends yesterday and I was the last alive against all 4 of them and they planted the bomb. I managed to get a Double by Quick Scoping, then I knifed the third guy, the last guy starting shooting at me from behind, but I pulled a 360 jumping no scope and killed him. I finished it off with a bomb defuse with 1 second left.
you sir are the matrix.
by the way i noticed that M4A1 + ACOG scope isn't that bad, the very low recoil makes it accurate and good to work with.
