## Official M4 numbers

Activision's launch weapon sheet gives the M4 810 RPM and a 30-round magazine with 90 reserve rounds. It unlocks at Player Level 14 and has 72 weapon levels. Among assault rifles its fire rate ranks 1 of 8 and its magazine ranks 1 of 8. Activision describes the M4 this way: Fully automatic, highly adaptable service rifle that Activision pitches as effective in most engagements. Its Apex Attachment is the M4 Hurricane. Converts the M4 into a top-loading, high-capacity 5.7x28 mm variant that is lighter, more agile and fires faster. It blocks barrel and magazine attachments.

Activision publishes no damage or time to kill.

## M4 pick rate, tier and time to kill
