Puncture mods go through objects and allies. For example if your target is taking cover you can continue firing and blow him away. Or, if an ally gets in your way of fire puncture mods will allow you to shoot through them ( no damage of course). Armor piercing mods reduce the damage reduction that Infested ancients and Grinner have, so your bullets do more damage per shot.
