Modern Warfare 3: Striker is the best build.

Modern Warfare 3  features an extensive list of weapons that pack a lot of firepower, with the Striker standing out as the most powerful SMG due to its consistent rate of fire, minimal recoil, and high mobility.

As with the MCW from Modern Warfare 3, this weapon is very similar to the UMP 45 from the original Modern Warfare 2 and 3. To be able to obtain the Striker and use it in your own loadouts in Modern Warfare 3 you will need to  reach level 4 level _

The Striker is typically most versatile at close range, but with our attachment recommendations, we’re going to build on those strengths while increasing its range and accuracy.

  • Muzzle:  Shadowstrike Suppressor
  • Barrel:  Striker Recon Long Barrel
  • Underbarrel:  XRK Edge BW-4 Handstop
  • Magazine:  48 Round Mag
  • Rear Grip:  Sakin ZX Grip

We start the Striker build with  the Striker Recon long  barrel, which provides extra bullet speed and damage range, combined with  the Shadowstrike suppressor,  which will hide your shots from the minimap. For the Underbarrel, we chose  the XRK Edge BW-4 hand rest  for increased mobility without any major drawbacks.

The 48-round magazine   will allow you to take down multiple enemies without having to reload, and finally,  the Sakin ZX Grip  helps control recoil so you’ll be accurate even at mid-range.

Perks:

  • Vest:  Infantry
  • Gloves:  Commando
  • Gear:  Ghost T/V Camo
  • Boots:  Covert Sneakers
  • Lethal:  Semtex
  • Tactical:  Battle Rage
  • Field Upgrade:  ACS

The Infantry  Vest  will improve your tactical sprint by reducing its cooldown and increasing its duration. The Commando Gloves will then   allow you to recharge while sprinting.

Additionally,  Covert  and  Ghost T/V camo  help you stay hidden while on the move by blocking detection of UAVs, radar sources, heart rate sensors, and muffling your footsteps.
