For Modern Warfare 2, we focused on increasing the overall damage, accuracy, and range in the M13B in this loadout.

Not to mention the overall ADS (Aim Down Sight) speed is also improved with contributions from the Bruen Flash Grip too. Adding to that, the 14” Bruen Echelon muzzle also improves the overall stats of the M13B, particularly in its range. For the optic, any red dot is beneficial, which is why we went for the Cronen Mini Pro.

The perk package for this assault rifle consists of the Scavenger and Overkill as the base perks. The Scavenger Perk will help you recover additional ammo from fallen enemies while Overkill will let you carry an additional primary weapon. Fast Hands is the Bonus Perk that will let you quickly reload and switch between weapons. Ghost as the ultimate perk will let you hide under enemy radars. For the throwable, a Frag Grenade or Semtex will do as the lethal option. And, for the tactical option, we went with the Stun Grenade.
