Spectra+Gunslinger=?

[Arlayn]

What does Fire rate do to a spectra if its already a laser beam? theres like no gap between any of the rounds. Does it make it do more damage more faster or what? if it does do more damage faster is it a good idea to have it, or better off with something else?

[Kroul]

Fire rate mods currenty do not affect the spectra and flux weapons.

[Wriith]

Currently continuous fire weapons are not affected by fire rate mods.  So to answer your question, gunslinger does nothing.

or better off with something else?

As other people said, it doesn't do anything. You're better off with a must-have mod like Barrel Diffusion, which actually increases the DPS.
