Why Hi-Cap Magazines?
A High Capacity Magazine (AKA "Hi-Cap") holds a larger amount of rounds than standard allowing the operator to play for longer between mag changes. This can be a huge tactical advantage and also means you usually never have to worry about running out of ammo in-game. Hi-Caps will make a slight rattle due to the large amount of rounds being held in the BB reservoir, but this slight noise is indistinguishable in the heat of battle. Simply outfit yourself with a few Hi-Caps and you are ready to rock!
