Assault Rifles

all six new assault rifles in modern warfare 3.

The new ARs in Modern Warfare 3 are SVA 545, MTZ-556, Holger 556, MCW, OG-58, and FR 5.56. Most of these weapons feature a burst-fire system, with two of them capable of shooting three-round bursts and one having a two-round initial blast.

Battle Rifles

all three battle rifles in modern warfare 3.

New BRs include BAS-B, MTZ-762, and Sidewinder. BAS-B has a low recoil, which suits mid to long-range combat. MTZ-762 shoots powerful 7.62 rounds at a fast speed, excellent for dropping multiple enemies. And Sidewinder is a 0.450 caliber beast with a long, deadly range.

Submachine Guns

SMGs, the most popular secondary weapons, dominate the new MW3 arsenal. With six brand-new options, including Striker, Striker 9, WSP Swarm, WSP-9, AMR9, and Rival-9, this category is set to be a major part of the metagame.

Light Machine Guns

the new modern warfare 3 lmg called bruen mk9.

Modern Warfare 3 adds five new firearms to the tried-and-true roster of LMGs in MW2. The new Light Machine Guns are Bruen Mk9, Holger 26, OG-58 LSW, Pulemyot 762, and TAQ Eradicator. Of these, the TAQ Eradicator seems to be a META. But it unlocks after completing an Unlock Challenge.

Sniper Rifles

the new sniper rifle in mw3 called the longbow.

On top of the seven SRs from MW2, Modern Warfare 3 will feature three new Sniper Rifles: KATT-AMR, KV Inhibitor, and Longbow. However, the .50 cal bolt-action KATT seems to be the only one-shot sniping option.

Marksman Rifles

the new marksman rifle in mw3 called dm56.

The new MRs in Modern Warfare 3 are DM56, KVD Enforcer, MCW 6.8, and MTZ Interceptor. While most of these firearms specialize in bolt/lever action and above-average mobility, the DM56 is the most promising addition, as it has the best-in-class fire rate with impressively low recoil.

Shotguns

the new modern warfare 3 shotgun called riverter.

With the three new Shotguns in MW3, there will be a total of nine scatterguns in the game. On top of the previous options, players can now boast Haymaker, Riveter, and Lockwood 680, all dominant in close quarters and excellent for hip-fire and Tac-Stance.

Pistols

the new tyr pistol in mw3 and warzone.

Hoping to balance the metagame both in MW3 multiplayer and Warzone, Activision has introduced four new pistols: COR-45, Renetti, TYR, and WSP Stinger. An ideal aspect of these firearms is their fast mobility and rapid swap animations, which make them reliable secondary weapons.

Knives & Launcher

the new gutter knife in mw3.

A new launcher called RGL-80 has made its way into the MW3’s weapon roster. However, players will also have two new melee choices, Gutter Knife and Karambit.
