Burst Rifle

The M16 appears in Operation Raccoon City, named the Burst Rifle. As its name suggests, it fires in three-round bursts. Though its model is based on A1 design. It sports an ACOG scope, which is fully usable in combat. It uses an uncurved, unique 21 Round Magazine, allowing it to fire 7 full bursts with each magazine. It has decent power and accuracy, making it capable of killing a standard zombie with one burst to the upper body, but it is recommended that players avoid close-range combat, due to the ACOG scope's zoom. The Burst Rifle also has a lower reserve ammunition capacity than the standard assault rifle.

The Burst Rifle does not appear in the USS campaign, but can be found multiple times during the Echo Six missions.
