## Official FiNN LMG numbers

Activision's launch weapon sheet gives the FiNN LMG 587 RPM and a 100-round magazine with 100 reserve rounds. It unlocks at Player Level 4 and has 59 weapon levels. Among LMGs its fire rate ranks 2 of 3 and its magazine ranks 1 of 3. Activision describes the FiNN LMG this way: Open-bolt, belt-fed LMG that is light, mobile and stable, with a high fire rate and strong recoil control. Its caliber is 5.56 mm. Its Apex Attachment is the FiNN Adverse. Tempest Armament modification that unthrottles the rate of fire. Sustained fire overheats the gun until it cools down. Activision lists no blocked attachment types for it.

Activision publishes no damage or time to kill.
