When it comes to building your weapon, the M4 is a reliable and trusty assault rifle so you are going to want to pick attachments that keep it on target, without providing many downsides. Our best M4 loadout for Modern Warfare 3 is:
As with all of our weapons, you want to start things off with the Cronen Mini Red Dot, which is the best sight in the game and just a great pick all around. Then, the FTAC Castle Comp is our muzzle slot which focuses on keeping the weapon’s recoil to a minimal amount.
Adding onto the setup, is the Hightower 20″ Barrel. This is key to the build, boosting your recoil control, damage range, bullet velocity, and hip-fire accuracy, all of which are either handy or vital to bringing out the effectiveness of this weapon. It comes with a few big downsides, but those are offset by the XTEN Grip which boosts your mobility with the weapon.
Then, finally, to end the build, you want to equip the Corio Precio Factory stock. This stock is unlocked super early on in the M4’s weapon-level track.
It gives the weapon even better aiming stability and recoil control, effectively turning the M4 into an absolute laser beam at any range. This makes it one of the most dominant ARs in the game.
Right now, the best secondary weapon for the Modern Warfare 3 M4 loadout is the X12. This is a simple pistol that excels at what it is meant to do, be a backup. There isn’t much choice right now but the X12 is better than the other pistol available early on.
When you are choosing your perks, you want to include base, bonus, and ultimate perks that really synergise well with the attachments and loadout you have built for your gun. That is why for base perks we recommend Double Time to boost your run and gun capabilities with the M4 and Bomb Squad.
Bomb Squad is particularly good right now as explosives deal a lot of flinch damage and damage generally, so this will help keep you on target when grenades come down your sightline. For the bonus perk, equip Fast Hands to boost the reload speed of the weapon which is a little too long for our liking currently. This will keep your gun up more often and avoid you from being caught off guard.
Finally, for the ultimate perk, you are going to want Ghost which is just as strong as it has always been. Even if you have to wait until later in the match to get the buff.
For your tacticals, equip the stun grenade to disorient your enemies and catch them off guard either up close or from afar and the Semtex or Drill Charge to have a trusty explosive or grenade in your back pocket. Finally, we recommend you run the Portable Radar or Battle Rage field upgrade which will enhance your sprint even further for a limited time and keep your health regenerating and you surviving while fighting. While the Portable Radar is best for those looking to sit back a little bit more and play things slow, allowing you to keep an eye on your surroundings.
And there you have our Modern Warfare 3 best M4 loadout with the best attachments and class set-up choices. With this loadout, you should be more than ready to go on some extended kill sprees and call in some of the higher killstreaks on offer in Modern Warfare 3 and be able to rank up fast using the weapon in one of the best Modern Warfare 3 loadouts.
