Best BAS-B loadout and attachments in MW3

Here’s the best possible BAS-B loadout against enemies in MW3:

  • Muzzle: VT-7 Spitfire Suppressor L
  • Stock: FSS Ravager-45 Stock
  • Magazine: 30 Round Mag
  • Optic: Corvus Mini Riser Optic
  • Rear Grip: STT88 Grip

The most crucial attachment you’ll need with the BAS-B is the 30-Round Mag. Since its default magazine only carries 20 bullets at a time, you will undoubtedly run out of ammo after every kill, so the extra capacity is necessary. If you want to hold down the trigger longer, then you can opt for the 45-Round Mag once you reach level 19, but your Aim Down Sight Speed and Movement Speed will take a considerable hit if you equip it.

There are still a few accessories, like the Muzzle: VT-7 Spitfire Suppressor L and the FSS Ravager-45 Stock (unlocked at BAS-B level 3), that can help keep your ADS speed and damage range at respectable levels. The former also raises your bullet velocity. You can also opt for the STT88 grip to improve gun kick control and firing aim stability.

The BAS-B is great at short bursts with medium-range targets

The default magazine only carries 20 rounds, meaning that spraying bullets isn’t ideal. Having to reload in the middle of a MW3 firefight is not a good outcome.

Best BAS-B gear and equipment in MW3

Use the following equipment with the BAS-B to gain an edge in the game:

  • Vest: Gunner Vest
  • Tactical Equipment: Flash Grenade
  • Lethal Equipment: Frag Grenade
  • Field Equipment: Trophy System
  • Gloves: Commando Gloves
  • Boots: Tactical Pads
  • Gear: EOD Padding

Now that the MW3 perks system has received a significant overhaul, the most essential part of your loadout will be the gear you wear. We recommend equipping the Gunner Vest as soon as you reach level 20 because it not only deploys you with max ammo but also improves your reload speed. It also grants you the Overkill perk, letting you equip another primary weapon. You don’t need an SVA 545 or an MCW 6.8 along with this weapon so consider a sniper rifle or shotgun. Commando Gloves are another helpful piece of equipment that enables you to reload while sprinting.

Next up, Tactical Pads are a valuable accessory that you can use with all loadouts since it increases slide distance, stance transition speed, and crouched movement speed. It also gives you the ability to fully ADS while sliding. Lastly, we recommend equipping the EOD Padding in your Gear slot because it reduces damage from non-killstreak explosives and fire, increasing your survivability. If you’re into stealth, consider the Ghost T/V camo to go under the radar of enemy players.

Of course, you can’t forget the classic Flash and Frag Grenade combo as your Tactical and Lethal Equipment when choosing the best BAS-B loadout in MW3, respectively. And since most players will be tossing these same utilities toward you and your team, the Trophy System ensures no stray grenade will take you and your squadmates’ lives.

Before you unlock loadouts at level 4, you can only use premade builds. You’ll be able to customize weapons after you cross this threshold.
