The best BAS-B loadout in MW3 is devastatingly strong as it melts enemies at mid to long-range in Season 1 multiplayer. As expected for a Battle Rifle, the BAS-B has an impressive 315ms TTK and with the right attachments, it's even possible to bolster its recoil pattern.

However, as the weapon is competing against ARs like the MCW, Holger 556, and SVA 545, it's key you optimise your build to squeeze every ounce of strength out of the BAS-B. That's where we can help, with the best BAS-B loadout in Modern Warfare 3 that's dominating the Season 1 meta.

Attachments

  • Muzzle: Shadowstrike Suppressor
  • Underbarrel: Bruen Heavy Support Grip
  • Magazine: 45 Round Mag
  • Rear Grip: STT88 Grip
  • Barrel: Wyvern's Repite Long

Kick off the best BAS-B loadout in MW3 with the Shadowstrike Suppressor for a muzzle that keeps you off the radar, but has no downsides to any of the gun's stats.

Follow this up with the Wyvern's Respite Long barrel that provides a huge boost in bullet velocity, as well as a nice balance of aim walking steadiness, and movement speed.

Next, you'll want to add the Bruen Heavy Support Grip and STT88 Grip to equip the gun with incredible firing aim stability, gun kick control, and of course, a laser beam recoil pattern.

Finally, as you'd expect, round off with the 45 Round Mag to keep you topped up on ammo and allow you to take out multiple foes with a single mag.

Perks

  • Gloves: Commando
  • Boots: Lightweight
  • Gear: EOD Padding
  • Vest: Infantry

Equipment

  • Lethal: Semtex
  • Tactical: Battle Rage
  • Field Upgrade: Munitions Box

Commando Gloves should be your first pick in the Perk category as it gives you the ability to reload while sprinting. This is essential as being able to reposition while topping up your mag will give you the best chance at winning your next gunfight.

Lightweight Boots paired with the Infantry Vest are a must for the ultimate mobility combo. The extra speed and tac-sprint refresh is perfect for MW3's fast-paced gameplay and means you can catch enemies off-guard with aggressive pushes.

In the Gear slot, EOD Padding will always be solid, as no one wants to die to an annoying Claymore or lucky Frag Grenade.

Equipment-wise, run a Semtex in the lethal slot for pushing enemies out of cover, Battle Rage as your Tactical to aid you in aggressive outplays, and of course, a Munitions Box is just a consistently useful Field Upgrade.

Battle Rifles are not for everyone, so if the BAS-B isn't quite making the cut for you, it may be time to grab a meta AR.

In our opinion, there's no better choice than the Holger 556, a weapon that hits like a truck at long range and is becoming a solid pick in Season 1. Currently sitting at number one in the popularity rankings, this is the go-to option if you want guaranteed success.

Our loadout for the weapon tempers its recoil while boosting its bullet velocity, making it top-tier for maps like Highrise, Terminal, and Skidrow.
