Long Barrel

Long Barrel is an attachment that appears in Call of Duty: Black Ops II. The Long Barrel increases the range of a weapon by 16%, therefore the longer the initial range is of a gun, the longer the maximum range will be. The attachment is available for Submachine Guns, Shotguns and Pistols.

Trivia

 * 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.
