## Official MAR-9 numbers

Activision's launch weapon sheet gives the MAR-9 315 RPM and a 20-round magazine with 60 reserve rounds. It unlocks at Player Level 4 and has 73 weapon levels. Among marksman rifles its fire rate ranks 1 of 3 and its magazine ranks 1 of 3. Activision describes the MAR-9 this way: Semi-auto marksman rifle with high-power precision and moderate recoil for medium to long range. Its caliber is 7.62 mm. Its Apex Attachment is the MAR-9 Auto. Fully automatic Bruen conversion with a high fire rate and more stopping power than the semi-auto original. It blocks trigger action attachments.

Activision publishes no damage or time to kill.

## MAR-9 pick rate, tier and time to kill

*Community tier and time to kill placements of the MAR-9*

| ggranked | MAR-9 Auto | Tier B | 966 ms | With Apex Attachment |
| DMZ Radar | MAR-9 | Tier B | Not reported | DMZ PvP tier, no time to kill published; unchanged |
