The juice is worth the squeeze.

One of the new weapons added all the way back in season one of Call of Duty for both Warzone and Modern Warfare 2 is a throwback.

The M13B is reminiscent of the Honey Badger from Ghosts, but its real-life counterpart is the SIG MCX. It has a “short-stroke piston system that allows for a high rate of fire and low recoil,” making it a decent option for close to mid-range.

Once you unlock the gun for usage by extracting it in DMZ mode or purchasing a bundle, you can bring it into Warzone via loadouts or buy one from a buy station. You’re going to need some powerful attachments for it, though.

Here’s the best set of attachments to unlock in the Gunsmith to use on the M13B in Warzone‘s season five.

  • Muzzle: Harbinger D20
    • Recoil Smoothness: +1.40oz
    • Bullet Velocity: +1.00in
  • Barrel: 14″ Bruen Echelon
    • Recoil Steadiness: +0.50lb
    • Aim Down Sight Speed: -0.40in
  • Optic: AIM OP-V4
    • Aim Down Sight Speed: -3.00oz
    • Far: -1.65in
  • Underbarrel: Phase-3 Grip
    • Recoil Stabilization: +0.80oz
    • Aiming Idle Stability: +0.40in
  • Magazine: 60 Round Mag

Assault rifles are often thought of as super-long-range options in Warzone, but the M13B is best suited for medium range. This can be maximized by throwing attachments like the ones above to increase its accuracy and recoil control.

The M13B pairs very well with a sniper rifle like the MCPR-300, turning the AR into a sniper support weapon rather than the main source of damage in a match of BR. But that doesn’t mean you can’t win some well-contested gunfights with it.

This setup makes the M13B feel something like an AR/SMG hybrid, like the classic Peacekeeper weapon from Black Ops 2. The 60 Round Mag is a nice addition, doubling the gun’s base ammo count and keeping you in the fight longer when you need to chunk down those purple three-plate armor foes.

In season five, the M13B has moved to the forefront of the meta thanks to nerfs on weapons like the RPK and Cronen Squall, so it’s time to bust this bad boy out again. I’ve been having lots of fun with it in Resurgence modes.

Best perk package for M13B loadout in Warzone

  • Perk Package: Double Time, Battle Hardened, Focus, Ghost

The best perk package in Warzone will keep you off the map and keep you moving quickly. Battle Hardened counters stun grenades and Double Time will keep you sprinting to or from the enemies in battle royale, while Ghost will keep you off of the enemy UAV.

Best equipment for M13B loadout in Warzone

  • Tactical: Stun or Flash
  • Lethal: Semtex or Throwing Knife

Flash grenades are incredibly strong in Warzone, as are stuns. Use whichever you prefer. The same goes for lethals, which are useful depending on how you’d like to use them. The throwing knife is perfect for throwing at a downed enemy for the kill and retrieving them to slay some more.
