can i get some sniper pro tips?
Barret 50 cal is the one to go for if you want one shot kills consistently
stopping power is a must if you want one shot kills, it doesn't need to be a headshot, any part of the body upwards of the waist will do
sleight of hand pro (quicker aiming down sights) and steady aim pro (hold breath for longer) help a lot in sniper classes
the ideal class to use for a sniper is:
rifle of your choice (i use barret 50 cal)
pp2000 or m93 raffica (the two best machine pistols)
claymores (to watch your back)
sleight of hand pro (to pull up scope quickly)
stopping power (to give you the power your need for those one shot kills)
steady aim pro (for when you need to hold your breath longer because your enemy ducked behind cover)
