Weapon Upgrades give an added bonus to Uncommon, Rare and Legendary quality Weapons. These vary drastically and some are more beneficial than others. They are mostly randomly distributed on Weapons that are acquired as drops, but some have static Weapon Upgrades that never change. The following are considered Weapon Upgrades and there are different pools for each weapon type.
Note: Only Legendary Weapons have more than 1 Weapon Upgrade, with a few special Rares being the exception. There are also a very few select Legendary Weapons that have static Weapon Upgrades that are not random. All Exotic Weapons have static Weapon Upgrades.
The following table is a list of all the possible Weapon Upgrades that are available in Destiny, which Weapon they can be found upon, which quality of Weapons they can be found on and what pool those upgrades are found in. This table shows what Weapon Upgrades could possibly be rolled and is true for MOST Weapons. There are some Weapons that this table does not apply to, namely a few select Rares and Legendaries. Exotics are not listed as they have static Upgrades that do not change.
