MCW (assault rifle)

The MCW assault rifle in Modern Warfare is known as one of the most versatile and easy-to-handle guns in the game. It is suitable for mid to long-range shooting as it has little recoil and a light frame.

Holger 556 Assault Rifle

Another best assault rifle choice in Modern Warfare 3 is the Holger 556 due to its superior range, accuracy, and reliability. It is preferred across professional leagues due to its low recoil, TTK, and portability throughout close-range and distance shooting. Additionally It is a general-purpose gun, a preferred weapon for those who aim to control the battlefield.

Rival-9 (SMG)

The Rival-9 SMG has become almost notorious due to its fast fire rate and powerful efficiency at short range. It excels in situations where the player engages enemies in close combat, delivering high damage rates and accuracy. With attachments like the Rival Vice Assault Grip and the Rival IGS-800 Barrel, it is possible to master the recoil and improve its performance in combat. Those who prefer an active play style, the Rival-9 is a hit among players at the top tier of the game.

FR 5.56 Assault Rifle

In both hip fire and aiming mode, the FJX Horus never disappoints and remains popular among professional players who value mobility and firepower.

Striker SMG

RAM-7 (assault rifle)

RAM-9 (SMG)

The RAM-9 SMG shines in MW3 due to its fast rate of fire and the ability to handle most close-range gunfights. Other attachments such as the Hunker 5 stock pad and the Speedway short barrel also reduce the amounts of recoil and improve its operation.
