Automatic barrel (Fallout 76)

The automatic barrel is a weapon mod in Fallout 76.

Effects
When applied to a plasma or Enclave plasma gun, the mod converts the weapon into an automatic weapon, increasing rate of fire and recoil while decreasing range and ammo capacity. It also decreases aimed and hip-fire accuracy.

When applied to a Tesla rifle, the mod converts the weapon into an automatic rifle, increasing rate of fire while decreasing range and aimed accuracy.

Location

 * The automatic barrel mod may be crafted and applied at a weapons workbench if the relevant plan is known. It can only be learned from scrapping weapons of the same type.
 * The automatic barrel mod for the Enclave plasma gun cannot be learned, crafted, or found as a loose mod. It may instead be found pre-applied to Enclave plasma guns sold by vendors or dropped as quest rewards.
 * Loose mods for the Tesla rifle may be randomly sold by Responder, Raider, Brotherhood, and Free States vendors. They may also be found randomly in various locations or earned as quest rewards in The Mire, Savage Divide, or Cranberry Bog. Loose plasma gun mods exist in the game files, but cannot be found in-game.
