FiNN LMG - Light Machine Gun specs

FiNN LMG at a glance

FiNN LMG is one of Activision’s 3 launch light machine gun entries. The official roster contains 33 weapons: 24 Primary Weapons, eight Secondary Weapons and one Melee Weapon. That total excludes Tactical and Lethal equipment, older cosmetic labels and duplicate Blueprint variants. This record uses the October 19 launch article, checked October 26, rather than treating earlier Beta cards as the current specification. FiNN is the open-bolt, belt-fed 5.56 LMG and has the largest base round count in this launch roster. Adverse increases firing rate and can overheat during sustained fire. The source does not specify the overheat threshold, cooldown time or converted RPM.

In-game description

An open-bolt, belt-fed LMG chambered in 5.56. Lightweight, mobile, and exceptionally stable, the FiNN pairs a high fire rate with advanced recoil control to provide outstanding accuracy in full-auto engagements.

The publisher’s description above explains the intended role of FiNN LMG. It should be read alongside its own numeric block: 59 weapon levels, 100 base rounds, 100 reserve rounds and 587 RPM. These are published fields, not measurements made by this wiki. Descriptive terms about power, stability or speed do not establish a damage table, a time-to-kill result or a tested advantage against a particular opponent. The configuration and mode still matter when interpreting such claims.

How it fits the class

Type 73 provides a same-class reference: its launch block lists 60 rounds, 60 in reserve and 821 RPM. FiNN LMG lists 100 rounds and 100 in reserve. Compare these base configurations before adding an Apex or a capacity attachment. A larger ammunition count describes ammunition available before replenishment; it does not establish more kills, a faster reload or better handling. Other class members are linked below so this comparison remains part of the complete roster.

Ammo and supply

The official launch reserve for FiNN LMG is 100 rounds, separate from the 100 loaded rounds. Reserve is ammunition outside the current magazine or feed, not a magazine attachment to add to its capacity. This entry does not infer a pickup amount, resupply interval or shared ammunition pool from a cartridge name. In DMZ, access and replenishment depend on the deployment and FOB systems; the article’s launch reserve field does not locate a specific ammunition cache or promise the same inventory after looting.

Magazine options

The launch block supplies 100 base rounds for FiNN LMG. Its attachment categories are listed separately below, and the article does not enumerate every magazine capacity or reload duration. Do not add a chambered round to the published figure or import an extended magazine from an older game. Any Apex description that explicitly changes the feed or capacity describes a different configured weapon. Keep the original base count visible so a later build comparison can distinguish the source specification from the selected attachment setup.

Gunsmith attachment slots

The published categories for FiNN LMG are Optic, Muzzle, Barrel, Underbarrel, Magazine, Rear Grip, Stock, Laser, Ammunition. Its Apex is FiNN Adverse. A Tempest Armament weapon modification that unthrottles the rate of fire beyond the weapon’s operational abilities. Sustained fire can overheat the weapon requiring the weapon to cool down before returning to full auto fire. Apex Attachments are equipped separately and do not consume an ordinary attachment slot, but the source may explicitly block individual categories for a conversion. Read those restrictions before planning a combination. Weapon progression unlocks shared attachments for compatible weapons, while Weapon Prestige relocks attachments on the weapon being Prestiged. The Gunsmith reference explains that progression context.

October 28, 2026 tuning changes

Infinity Ward published these figures in the first MW4 weapon tuning pass, dated October 28, 2026. The full pass covers fifteen weapons and is collected on the weapon tuning page.

Stat	Pre	Post	Change
Mid Damage Range 1	1720	1620	−6%
Left Upper Arm Damage Multiplier	1.1	1	−9%
Right Upper Arm Damage Multiplier	1.1	1	−9%

What is not measured yet

Infinity Ward states that Multiplayer and DMZ have bespoke tuning. Record the mode, patch date and exact configuration when measuring damage, recoil, effective range or time to kill; published cyclic rate alone cannot supply those results. The October 23-25 patch notes distinguish implemented fixes from proposed future tuning.

How to unlock it

FiNN LMG’s weapon detail block lists Player Level 4. Its individual Available Criteria entry agrees: Unlocked at Player Level 4. This is a player progression requirement, distinct from the 59 weapon levels listed for attachment progression and access to Weapon Prestige. Create-a-Class opens at Player Level 4. In DMZ, unlocked weapons can be purchased through the FOB Gunsmith with sufficient DMZ Cash; looting, Weapon Manuals and the FOB Vendor provide other acquisition routes described by Activision. A cosmetic Blueprint name is a separate entitlement, rather than a replacement for these base progression rules.
