Ammo regeneration

There are two basic categories of ammo regeneration.
 * 1) Alien Guns rebuild their internal ammo over time. Each weapon is separate.
 * 2) Everything Else. Ammo is added to the affected player's SDU until it is full or the effect is removed.

There are a variety of ways to gain ammo regeneration. Brick & Roland both have skills] that will do the trick. Roland (and possibly others?) have class MODs that will do it.  There are a number of different weapon attributes that will do it.  See [[Special Weapon Effects for details there.  Guardian and Equalizer spring to mind, both from Tediore.

Roland's Scorpio Turret can grant anyone near it ammo regeneration if he purchases Stockpile for the weapon they are currently holding.

Rolands Support Gunner class mod grants him and all his team mates ammo regeneration.

All characters have at least one class mod that will grant them ammo regeneration for a particular weapon type.
