Haven't seen anything like that, but it's something you can easily test yourself with Rangefinder in VR training. Well, the damage is easy to test, rate of fire and velocity will be harder to find out.
It has the same sound (and presumably ROF - 550 RPM) as the kobalt, but seems a tad weaker per bullet, probably 167 Max instead of 200. Also, the kobalt has a smaller COF and probably smaller max bloom too. Essentially the mana turret is an inferior kobalt with a heat mechanic.
