The improved automatic barrel is a weapon mod for the Institute laser, the laser gun and the plasma gun in Fallout 4.


The improved automatic barrel provides a superior rate of fire, improved damage range and sighted accuracy in exchange for worse recoil, reduced ammo capacity and poor hip-fire accuracy.
