Long Barrel is an attachment featured in Call of Duty: Black Ops II.


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 Pistols. It is incompatible with the Supressor attachment.


  • 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 is comparable to the Range Proficiency from Call Of Duty: Modern Warfare 3, though available on more weapon classes and unlocked much sooner.
  • The Long Barrel icon uses the M8A1 barrel, despite that the attachment is not available for Assault Rifles.
