Best Modern Warfare 3 M4 attachments

After some testing, this set of five is perfect for dominating with the M4 in Modern Warfare 3:

  • Barrel: Hightower 20" Barrel
  • Optic: Slate Reflector
  • Stock: Demo Fade Pro Stock
  • Underbarrel: FTAC MSP-98 Handstop
  • Rear Grip: Sakin ZX Grip

Up first is the Hightower 20" Barrel which provides the improvements to damage range and bullet velocity. To stop any unwanted recoil from ruining your accuracy, the pairing of the Demo Fade Pro Stock and the Sakin ZX Grip is a surefire way of ensuring the bullets hit the target every single time.

For a boost of sprint speed, the Demo Fade Pro Stock comes into its own alongside the Slate Reflector optic which provides a crystal-clear view of the action.

Best Modern Warfare 3 M4 perks and equipment

Once the best M4 attachments are ready for battle, selecting four perks and two pieces of equipment is the next step to building the strongest loadout. Here are our recommendations.

Perks

  • Vest: Infantry
  • Gloves: Quick-Grip
  • Helmet: EOD Padding
  • Boots: Stalker

This combination of perks aims to improve movement speed when using the M4 in the heat of battle. The Infantry vest increases the length of Tactical Sprint, while Quick-Grip gloves give you the option to switch to your secondary weapon as fast as possible.

For some additional resistance to incoming explosives, EOD padding is a surefire way of staying in amongst the action for longer. Lastly, Stalker boots feature faster strafing and aim-down sight speeds that are perfect for improving reaction times.

Equipment

  • Lethal: Semtex
  • Tactical: Stun Grenade

The combination of Semtex and Stun Grenade is hugely versatile. Stick a Semtex through a window to clear out any potential campers, and to stop a potential target from escaping your view. Chuck a Stun Grenade to slow their movement enough to secure the kill with minimal resistance.
