How many rounds per minute is the max effective rate of fire for the M4 in burst mode?

The maximum effective rate of fire for the M4 carbine in burst mode is 90 rounds per minute. This rate is established based on the weapon's design and operational capabilities, taking into account the mechanics of the burst firing system, which limits the rifle to firing a three-round burst with a single trigger pull. This approach optimizes accuracy and control, allowing soldiers to engage targets effectively while managing recoil.

Understanding the effective rate of fire is essential for operational planning, training, and tactical engagements, as it directly impacts ammunition consumption and combat efficiency.
