Laser Pistol, Pew Pew[unique laser pistol], Laser Rifle, AER14 Prototype[unique], Tri-Beam Laser Rifle, Laser RCW and the Gatling Laser
Alright here's what Laser commander does 15% more damage and 10% to critical hits[modified by the weapons chance modifier].
I feel the best example of its power is on the AER14 laser rifle, Now with max energy weapons and laser commando the AER14 will deal about 40dmg base. It has a x2 critical mod so that +10% to critical becomes +20%. Add in your luck, finesse, bones hat and the set lasers for fun challenge perk and you can have a really high critical rate, which means a lot more damage especially if better criticals is taken.
