Call of Duty Multiplayer Help: Extended mag

Call of Duty Multiplayer has TONS of gun mods and one is
  Extended mag, It pretty much explains itself, MORE AMMO!

It helps alot when rapid fire guns and goes awesome with scavenger.

So you run around with even more ammo in a single clip using Extended mag so you have that much more of an advantage over the enemy.

With rapid fire you blow through a normal clip in seconds at least with Extended mag you have the few extra bullets which always counts.

   -Stay frosty and DOMINATE Call of Duty Multiplayer!
