This is the ultimate BAS-B MW3 loadout to turn this meta battle rifle into a true powerhouse capable of dominating every multiplayer lobby thanks to its phenomenal damage output.

Due to its early success, the BAS-B was the target of a few nerfs in Season 3. This might make you think it is no longer worth using but that isn’t the case. It is still a fantastic battle rifle that competes with the best guns in the meta.

However, it’s no longer quite as easy to build without having to think about what attachments work best. This guide simplifies that process for you by listing the best BAS-B loadout in MW3, picked to make this as well-rounded as possible. Let’s get right into it.


Best BAS-B MW3 loadout in Modern Warfare 3


  • Optic: Quarters Classic Reflex
  • Underbarrel: Bruen Heavy Support Grip
  • Stock: Ravage-20 Heavy Stock
  • Rear Grip: STT88 Grip
  • Magazine: 30 Round Mag

In its base form, the BAS-B doesn’t produce too much recoil but it is still worth using the Ravage-20 Heavy Stock and the STT88 Grip. These help to significantly improve the gun’s recoil control and firing aim stability, especially when using it in full auto which is recommended to get the best TTK possible.

The Bruen Heavy Support Grip helps further mitigate its recoil. With all three of these attachments combined the BAS-B is a remarkably accurate gun that is effective both up close and from afar. Despite being a battle rifle, it is a true jack-of-all-trades primary weapon that just about anyone can use.

Something to note about the BAS-B is that its relatively low fire rate can make missed shots especially costly. Due to this, it’s highly recommended to use an optic with a clear reticle like the Quarters Classic Reflex. This red dot sight isn’t just nostalgic, it’s also one of the easiest to use in MW3 Season 3.

Another con of this rifle is that its magazine only holds 20 rounds by default which will leave you constantly reloading. Thankfully, this is easily solved by equipping the 30 Round Mag, providing 50% more shots per mag, and making it much easier to chain kills together.

BAS-B MW3 loadout: Perks & Equipment

  • Vest: CCT Comms Vest
  • Gloves: Marksman Gloves
  • Boots Lightweight Boots
  • Gear: Mission Control Comlink
  • Gear: Mag Holster

The CCT Comms Vest is an interesting option as it excels in gaining intel and marking enemies at the expense of lethal and tactical equipment. This works well with the aggressive playstyle suited to our BAS-B build.

For Gloves, the Marksman Gloves work well practically negating all flinch and idle sway while aimed in. Since battle rifles in MW3 have relatively low firing aim stability this is a great option to offset that weakness.

To make getting around the map easier you’ll also want to use the Lightweight Boots. These increase both movement and swim speed which is great for getting into power positions quickly and controlling key areas of each map.

Mag Holster is an obvious choice for Gear given the BAS-B has a fairly slow reload compared to other comparable guns. This is especially true with the 30 Round Mag equipped which results in a full reload taking well over 3 seconds. Finally, Misson Control Comlink makes killstreaks easier to earn giving you a better chance of calling them in and taking over a match.

How to unlock the BAS-B in Modern Warfare 3

Players can unlock the BAS-B by reaching Level 17 in Modern Warfare 3. Alternatively, successfully extracting a BAS-B in Zombies will also unlock the battle rifle.

Best BAS-B alternative in Modern Warfare 3

A great alternative to the BAS-B is the SOA Subverter, which is one of the best battle rifles as of MW3 Season 3. It boasts nearly identical stats to the BAS-B, minus all the nerfs, with a decent rate of fire and solid damage if you hit your shots.
