Attachment slots

The FiNN LMG has 9 attachment categories. In MW4 you unlock each attachment once, and it then works on every weapon that accepts it.

We are not publishing our own attachment-by-attachment build until we have tested this weapon in the launch version. Until then, the in-game Gunny optimizer in Create-a-Class and the FOB Gunsmith can suggest close-range, balanced and long-range builds from the attachments you own.

Apex Attachment: FiNN Adverse

Removes the fire-rate limiter. Sustained fire can overheat the gun and force a cooldown before full-auto works again.

Getting the FiNN LMG in DMZ

The FiNN LMG unlocks at player level 4, the same level Create-a-Class opens, so it is available from the start.

In DMZ the player level only matters for leveling, because weapon levels and attachment unlocks are shared with Multiplayer. To actually carry a FiNN LMG into Hajin:

Any FiNN LMG you extract with can also be upgraded at the Gunsmith as a one-off copy. You can carry two weapons in and out of a deployment, or more with a Weapon Backpack.
