My favoritest sniper is the M24, because it's sexually accurate. After that is the L9, because it's a quickscope smex machine.
Btw:
M24 = second strongest SR
SVD = 3rd
MSG-90 = 4th
SR25 = 5th.
ALL of them are two hit kills, except for the SR25 when you're attacking a heavy vester. Then, and only then, is it 3. But you're shoot so fast it doesn't matter. If you have good internet, unlike me, they'll be dead before it registers your first hit on their computer.
