The BAS-B battle rifle has already made its way to the hearts of players as one of the best guns inCall of Duty: Modern Warfare 3. It outperforms many assault rifles in mid-range fights, and it can rival even SMGs in CQB when kitted out for speed and handling.
Players who are looking for a versatile weapon inCall of Duty: Modern Warfare 3MP or Warzone have a lot to look forward to with the BAS-B. With the proper attachments, this gun can easily contend with some of the more specialized weapons in the game. Here are two loadouts for players who want to use the BAS-B for close and medium ranges.
Updated July 10, 2025, by Marc Santos:With the launch ofModern Warfare 3andWaarzone Season 1,the BAS-B’s semi-auto firemode now deals more damage per shot just like other battle rifles. This guide has been optimized to account for that change, and a new section dedicated for a BAS-BWarzoneloadout has been added as well.
MW3 BAS-B Mid-Range Build
Like most automatic rifles, the BAS-B excels inmid-range gunfights by default. It packs a mean punch while still having manageable recoil, making it great even without any attachments. However, it only gets better once players do start tinkering with its stats.
The followingMW3BAS-Bsetup focuses on extending the weapon’s effective range by reducing recoil even further while enhancing its accuracy:
One of the biggest advantages of the BAS-B inMW3is its clean stock iron sights. Attaching a scope or red dot doesn’t feel as mandatory on this gun compared to some others, which means players get one additional slot for attaching a stock or magazine mod. Keep this in mind when making other BAS-B builds. For even better recoil control, use the Ravage-20 stock in place of a sight.
MW3: BAS-B Close-Range Build
Since the BAS-B is counted as a battle rifle, expect it to have slower overall handling compared to other primary weapons. However, this can be bypassed to some extent, turning the rifle from a mid-ranged corridor camper to a close-range carbine high stopping power. This CQBMW3BAS B build is as follows:
With the attachment setup above, the BAS-B’s recoil will increase dramatically. It will be much harder (though not impossible) to use from a distance, but it will be quicker on the draw and more reliable when used while hip-firing or whenshooting from Tac Stance.
This loadout changes how the gun feels completely. Players should use this if they want to flank and win fights at very close range. They’ll still get outgunned by SMGs like the Fennec or the AMR9, but this BAS-B CQB build should give them a better shot at winning against those weapons.
ThisWarzoneBAS-B loadout focuses more onstabilitythan recoil control, which allows foreasier follow-up shots. Aiming Idle Sway helps keep players on-target as they shoot from afar, while Firing Aim Stabilityreduces the overall shakiness of a weaponwhen firing in full-auto. Horizontal recoil reduction is preferred over vertical, since the former is harder to manually compensate for in long-ranged fights. This setup has an effective range of 42.7m, with a minimum damage range of 64m.
Since players are generally more durable inWarzone,having a larger magazine for the BAS-B is a must. The 45 Round Mag should provide more than enough firepower to handle a trio of enemies. However, players who prefer to be less sluggish can use the 30 Round Mag instead.
Due to the BAS-B’s slow reload speed, bringing a reliable secondary weapon is highly recommended.An SMG like theWSP SwarmorFenneccan fill in for the BAS-B in CQB. Players can freely choose which attachments they want for these weapons, though a hipfire or Tac Stance build with extended mags is the most ideal.
Perks
Sleight of Hand is here to compensate for the slower reload speeds of extended magazines. The other three are generally useful for resisting negative effects, regenerating equipment, and hiding from radar sources. There’s plenty of room for changes here, and it’s up to the player to determine which perks they want to swap out.
