Since the COD MW3 update players have discovered many new best weapons. To maintain the advantage in the next game, we need to recreate the weapons we use and upgrade them. So, how do we quickly upgrade guns in COD MW3? This article below will show you some effective ways to upgrade your weapons.

1. Kill Opponents

There is no way to raise your weapon level other than by defeating your opponents. Use your weapon of choice and engage in as many battles as possible to gain experience points (XP). To upgrade our weapons, we need to invest a lot of time, and if you are bored with this, then you can get COD Boosting services at U4GM, and they will drop everything you need.

2. Use 2XP Weapon Level Tokens

These tokens can be obtained as campaign rewards or by completing challenges. Using a 2XP token will double the weapon level XP you gain for a limited time, allowing you to level up your weapons faster.

3. Play Objective Modes

Some objective modes available in MW3 include Search and Destroy, Domination, Hardpoint, Control, and Headquarters. These modes require players to complete specific objectives, such as capturing and holding points, planting bombs, or defending objectives, to earn points and win the game. Playing objective modes can be a good way to earn more weapon XP and level up faster in MW3.

4. Play Zombies Mode

This mode allows you to level up weapons quickly by killing zombies and earning weapon XP. You can also use the fast XP method by packing-a-punch and calling in the helicopter to spawn a swarm of zombies for quick XP gains.

5. Use Decoy Grenades

Place decoys while playing Invasion mode to attract AI-controlled soldiers, which can be killed for XP. It can be used to trick and easily take down enemies by creating fake gunfire and radar signatures, allowing players to flank unsuspecting opponents.

6. Play DMZ

This mode offers a good balance between player and AI-controlled opponents, allowing for efficient XP farming. You can level up your weapons by using a specific weapon in DMZ and completing various objectives, such as killing enemies and completing contracts. However, remember that you will lose access to your insured weapon for a few hours if you cannot extract it, so be cautious while playing.

Remember that leveling up weapons will unlock additional attachments and provide cosmetics that change your weapon’s appearance. By following these methods, you can level up your guns in MWZ quickly and efficiently.
