The Avenger's rate of fire was originally selectable,
2,100 rounds per minute (rpm) in the low setting,
or
4,200 rpm in the high setting.
Later this was changed to a fixed rate of 3,900 rpm.
In practice, the cannon is limited to one and two-second bursts to avoid overheating and conserve ammunition; barrel life is also a factor, since the USAF has specified a minimum life of at least 20,000 rounds for each set of barrels.
There is no technical limitation on the duration the gun may be continuously fired, and a pilot could potentially expend the entire ammunition load in a single burst with no damage or ill effects to the weapons system itself.
However, this constant rate of fire would shorten the barrel life considerably and require added barrel inspections and result in shorter intervals between replacement.
