I feel like this should be an item to use on weapons, xp depending on status/rarity (I II III) and should be given when completing 3 tasks of 1 section and a level II on 2 sections, and III on 3 sections, and should be given by drops and or crates. These would come in handy, or you could add a xp converter where you take a weapon and put it in a slot that would be given xp, and then a bar for weapons of any rarity which will give a certain amount of xp and will be salvaged to that chosen gun. This would be awesome!
