It uses standard pistol ammo, which means it shares its ammunition supply with other pistols and handguns. In its Far Cry 4 incarnation, it can be fitted with a suppressor, an extended magazine, or one of several sights although it is limited to two of the previous at any given time due to only having two mod slots. The A99 is unlocked after completing the mission Payback. The A99 as it appears in Far Cry 4 sports a high cyclic rate of fire, along with being able to be used in a sidearm slot. Its ease-of-use and stopping power are renowned. This full-auto machine pistol has been banned in a number of countries.
