The improved long barrel is a weapon mod for the Institute laser and the laser gun in Fallout 4. It requires at least rank 2 of the Science! perk.


The improved long barrel provides better damage and range, improved sighted accuracy and recoil in exchange for reduced ammo capacity and poor hip-fire accuracy.


The recipe for this weapon mod varies depending on the weapon for which it is made:

Crystal (1-4)
Glass (0-4)
Screw (4)
Silver (4)
