Long Barrel is an attachment featured in Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified and Call of Duty: Black Ops III. It was also cut from Call of Duty: Modern Warfare Remastered.

The Long Barrel increases the range of a weapon by 16%. Therefore, the longer the initial range of a gun is, the longer the maximum range will be. The attachment is available for submachine guns, shotguns and handguns. It is incompatible with the suppressor attachment, for balancing reasons.

Call of Duty: Black Ops: DeclassifiedEdit

The Long Barrel appears as an attachment for several weapons in Call of Duty: Black Ops III. It functions a lot differently compared the long barrel from Call of Duty: Black Ops II.

The long barrel change every weapon category differently:

  • Submachine Guns will get a 25% increase in their maximum range
  • Shotguns will only get a 13% increase in their maximum range (meaning it does not help with one-shot kills)
  • Handguns will get a 13% increase to all ranges
  • Assault Rifles will have doubled range with long barrel

Aesthetically, it adds an extension to a weapon's muzzle. It is now compatible with the Suppressor barrel attachment.

The Long Barrel was a planned attachment for Call of Duty: Modern Warfare Remastered[1], referenced with strings in the game files.


Call of Duty: Black Ops IIEdit

  • The only weapons to actually change appearance cosmetically when outfitted with the Long Barrel are the Executioner and the Olympia
  • The Long Barrel doesn't actually increase the damage inflicted. Despite the statistic increase, rather it increases the distance of the damage drop-off by increasing the range.
  • Menendez's Executioner in "Odysseus" has a long barrel attached, while in "Achilles' Veil", it has a standard barrel.
  • The Long Barrel icon uses the M8A1 barrel, despite the attachment not being available for Assault Rifles.
