From Destinypedia, the Destiny wiki
Trace Rifles are powerful rifles capable of firing singular, concentrated energy beams that can be focused down upon multiple targets at once. They are under the energy weapon category. Because of the low amount of known rifles, they were instead infused with Auto Rifles until the introduction of Upgrade Modules. All trace rifles wieldable by Guardians are of Exotic rarity, except for the Retraced Path.
