Update: Our best MW3 BAS-B loadout was updated with new and alternative attachments to be up to date with changes made to MW3 since its launch.

Modern Warfare 3 has a range of weapons for you to experiment with, and plenty have already proven to be some of MW3's best guns. One such weapon that you can grab and fly around maps with early on in MW3 is the BAS B battle rifle. This versatile rifle is slow to begin with, but our best MW3 BAS B loadout shows you how to get the most out of this weapon.

In this guide, we explain all the attachments, gear, and equipment you need to grab yourself some impressive killstreaks with the BAS B in MW3.


MW3 best BAS B loadout: best attachments

The BAS B - not to be mistaken with the BAS P from MW2 - is an interesting and impressive battle rifle. This particular loadout will focus on giving it a faster time to kill, improved mobility, and fantastic recoil control so that we can quickly tear through enemy targets. This particular loadout is thanks to Cbass, and boasts an incredibly fast TTK to combat MW3's increased health pool.

  • Barrel: Wyvern's Respite Long Barrel
  • Underbarrel: Kimura RYN-03 Vertical Grip or XTEN Phantom-5 Handstop
  • Muzzle: T4LR Saber Compensator L
  • Magazine: 30 Round Mag
  • Laser: Cronen Intlas MSP-12

For this particular BAS-B loadout, we won't be using a suppressor. That said, if you prefer staying hidden from enemies on the radar, you can choose to add one in place of another attachment instead.

To kick things off, we're using the Wyvern Respite Long Barrel as our BAS-B's barrel. At detriment to our accuracy, we'll gain some additional range and damage to play around with, as well as a little bit more mobility.

As for our underbarrel, we're using the Kimura RYN-03 Vertical Grip which will help us to regain some accuracy. It improves our gun kick control, vertical recoil, and stability while reducing our speed a minimal amount, so we can still be fast to fire while also accurate with the weapon. The XTEN Phantom-5 Handstop is also a great alternative to use.

The T4LR Saber Compensator L as a muzzle for the BAS-B will also benefit this build by granting us even more vertical recoil control and some stability when firing, so we can consistently hit our targets. That said, this muzzle can easily be replaced by another one that helps your firing stability further, if this isn't the muzzle for you.

A necessity for this particular loadout is a magazine. The BAS-B has 20 Round Mags, which with MW3's increased TTK, just isn't enough. We recommend adding a 30 Round Mag to the BAS-B, but if you can handle the cons of it - a lack of speed - the 45 Round Mag can be considered too.

Last, but not least, we're going to add a laser to the BAS-B to make our shots that little bit more snappy. The Cronen Intlas MSP-12 is a great option, providing us with additional stability and a very fast ADS speed. That said, you will have a laser on your gun revealing your location; if this isn't for you, we recommend adding a suppressor or alternative optic attachment that doesn't have a laser glaring from it.

Now, any attachments that don't take your fancy could also be swapped out for a rear grip. For our BAS-B's rear grip, the STT88 Grip will help us with our ability to control the gun by providing some increased recoil control, gun kick control, and firing aim stability so that we can use the gun with ease.

MW3 best BAS B perks and equipment

Now that our BAS B loadout is established and we’ve got a sturdy battle rifle in our hands, it’s time to run through what equipment compliments the weapon.

  • Secondary Weapon: Renetti
  • Vest: CCT Comms Vest - provides three gear slots and one equipment slot (Lethal and Tactical are removed). Increases duration that enemies stay on the radar for you and nearby allies. Enemies will also drop intel packs.
  • Gloves: Scavenger Gloves - Allows you to resupply ammo and throwing knives from dead players. Quick-Grip Gloves could also be used.
  • Boots: Lightweight Boots - Increases movement and swim speed.
  • Gear: Mag Holster - Improves reload speed.
  • Gear 2: Ghost T/V Camo - While moving, blocks detection by UAVs, enemy radar sources, and Heartbeat Sensors. EOD Padding can also be used.
  • Field Upgrades: Munitions Box or Trophy System - you can never go wrong with more ammo, but the Trophy System can destroy nearby equipment and projectiles.
