Springfield (accuracy but use ptrs when you unlock it)
Walther (high rate of fire, accurate, big clip, no recoil and good damage.)
Frag Grenade
Smoke (distraction, escape from other snipers, and relocate.)
Bouncing Betties
Stopping Power (unless hardcore)
Iron Lungs ( extreme conditioning, dead silence if you didnt unlock Iron lungs)
Hope that helped
