Laser Gun (Fallout 4)

The AER9 laser gun is a weapon in Fallout 4. Variants include the laser pistol and laser rifle.

Gameplay
Compared to the similarly modified Institute lasers, laser weapons offer superior damage with a slower rate of fire, however can do more DPS when fully modified. They can be found throughout the Commonwealth, but are particularly popular with the Brotherhood of Steel and the Gunners.
