For a weapon proficiency with a similar effect, see Range.

The Long Barrel is an attachment featured in Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty: Black Ops III, Call of Duty: Black Ops 4 and Call of Duty: Mobile. 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. This is most effective on shotguns, as it increases the maximum range the pellets can hit a target before vanishing. On handguns, it's not as effective, except for the Executioner, where it makes the weapon much more effective. It also adds a physically longer barrel to the weapon as well.

The Long Barrel returns as the Extended Barrel.

Call of Duty: Black Ops III

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

The long barrel changes every weapon category differently:

• 100% longer range for all assault rifles except KN-44 and KVK 99m.
• KN-44's range is increased by 13% and KVK 99m's range is increased by 30%.
• Submachine guns have their minimum damage range increased by 25%.
• Shotguns have their minimum damage range increased by 13% and minimum base damage decreased by 20% (meaning it does not help with one-shot kills, but allows them to reach further with decreased damage).
• Handguns have their range increased by 13%.

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, referenced with strings in the game files.

Call of Duty: Black Ops 4

"Increased damage falloff ranges."

— Description

The Long Barrel reappears in Call of Duty: Black Ops 4.

Some weapons allow players to attach the optional Long Barrel II after the normal Long Barrel is equipped. The weapon's range is greatly increased when equipping two Long Barrels.

Call of Duty: Mobile

In addition to the multiple barrel customizations, the attachment appears in Call of Duty: Mobile as the Extended Barrel, also referred to as RTC Tac Impaler in the attachment unlock screen. It is available to the BY15 and KRM 262 shotguns.

Call of Duty: Black Ops Cold War

"Extended shotgun barrel with chrome lined bore. Improves damage range."

— Gallo SA12 Gunsmith description

Within Call of Duty: Black Ops Cold War, the Long Barrel returns as the Extended barrel family of barrel attachments, giving increased muzzle velocity for most weaponry it can be attached to. However, it gives increased effective range for Shotguns, along with a reduced movement speed while aiming for the XM4.

Trivia

Call of Duty: Black Ops II

• 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 to assault rifles.
  • This icon reappears in Black Ops III.
