The BAS-B is the first battle rifle you unlock in Call of Duty: Modern Warfare 3. Ironically, it’s also one of the best battle rifles in the game, and we’re going to tell you exactly how to build it for maximum performance!
A big favorite in MW3, the BAS-B is a battle rifle that operates fully-automatic, meaning it’s basically a heavier, more powerful assault rifle. It definitely needs some help in the Gunsmith to turn it into a formidable weapon online, but thankfully, there’s a version in the Commando default class that provides a ton of inspiration.
Here are the ideal attachments and equipment needed to make the best BAS-B loadout in MW3.
Best BAS-B loadout in MW3 multiplayer
The best BAS-B MW3 loadout features equipment and perks that maximize the ability to deal its powerful damage accurately and at range. That’s why I love these attachments, which buff damage, range, and recoil control while using the full-auto fire.
Best BAS-B build in MW3 multiplayer
- Barrel: Bruen Venom Long Barrel
- Stock: Bruen LAUR4 Light Precision Stock
- Underbarrel: XRK Edge BW-4 Handstop
- Magazine: 30 Round Mag
- Rear Grip: STT88 Grip
Getting your BAS-B magazine size up to a sturdy 30 is an easy decision, especially considering it’s a full-auto weapon, so I like to find the middle ground between its base mag of 20 and the maximum of 45.
With the attachments above, the base BAS-B’s lack of proficient recoil, fire rate, and magazine size are all addressed, giving it an almost pin-point accuracy.
The only change I recommend is potentially swapping out the Bruen Venom Long Barrel for an optic, like a Slate Reflector or the MK. 3, if you prefer not to use iron sights.
Best BAS-B class in MW3 multiplayer
- Vest: Infantry Vest
- Secondary weapon: WSP Stinger
- Tactical: Flash Grenade
- Lethal: Semtex
- Field Equipment: Trophy System
- Gloves: Marksman Gloves
- Boots: Stalker Boots
- Gear: Tac Mask
The best BAS-B MW3 loadout features equipment and perks that maximize the ability to deal powerful damage accurately and at range. That’s why I love Marksman Gloves, which reduce sway and flinch while aiming down sights, which you’ll be doing a lot with this gun.
Stalker Boots will allow you to strafe faster while aiming, while Tac Mask will prevent you from getting stunned as enemies try to flush you out of your position. Grenade choice depends on your preference, but I’ve found that this rifle does exceptionally well if you lead medium-range encounters with a quick flash and Semtex before moving in.
Now that you know the best BAS-B build and loadout in MW3, you can now get out there and become the try-hard you were meant to be.
