- "This hyper-advanced barrel is more than simply a barrel. Holding the trigger charges the rifle and releasing fires a single, high-power energy projectile."
- — In-game description
The Photonic Charge Barrel is a Barrel for the MORS Sniper Rifle featured in Call of Duty: Modern Warfare III as part of the Aftermarket Parts system. It was added as part of the Season Three update.
This barrel allows the MORS to charge up before firing to increase damage and velocity, at the cost of lower velocity and damage values when uncharged. While it does deal increased damage when fully charged, it will not exceed its base velocity when fully charged.
