The .38 receiver is a weapon mod for the combat rifle, the hunting rifle, the pipe bolt-action pistol and the pipe revolver in Fallout 4.


The .38 receiver converts the ammunition type that the modded weapon uses to .38 rounds. It provides reduced damage in exchange for a more common type of ammo in the Commonwealth.


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

Adhesive (4-7)
Aluminum (6-12)
Gears (2-6)
Oil (3-6)
Screw (4-8)
Icon range
Gun Nut (2-4)
Icon level
.38 receiver (1)

Hunting rifle 3 7 10 4 5 8
Pipe bolt-action pistol 2 4 6 2 3 4
Pipe revolver 3 4 6 4 3 5


  • Can be attached to gun via a weapons workbench.
  • If a gun has it equipped and it is replaced with another mod, it will go into the player's inventory.
