The list below depicts the Sight Upgrades available on each Special Weapon ( Fusion Rifles are the only ones with Sight Upgrades). They are separated into the pools that the same Sight Upgrades can come from (the pools shown are for Rare and Legendary weapons, Uncommon pools are slightly different and they only have 2). Upgrades in (Pool 1) will NOT be randomly generated in a different pool, etc. The colored circles on the right side of each upgrade delineate which quality of weapon the upgrade can be found upon. Exotics have static upgrades and are listed in their individual pages.
