Warzone’s assault rifles remain the battle royale’s most popular form of weaponry thanks to their versatility and ease of use. But which stand out from the pack? Here are the top five best assault rifles in Warzone Season 4, ranked. 

Season 4 of Warzone and MW2 has now given way to the mid-season Reloaded update, which dropped on July 12. It brought more weapon buffs and nerfs, especially to weapons in Modern Warfare 2.

Regardless, our recommendations for the best ARs in Warzone have changed, thanks mainly to the overhaul weapon damage profiles received in S4R.

5) Tempus Razorback

For the first time since its implementation, the Tempus Razorback AR makes the cut. It’s fast fire-rate, solid handling and decent range make it a strong weapon at medium ranges, even if it bounces slightly more than we’d like. As a result, it struggles to stay ultra viable at longer distances, but our chosen attachments make it a lot easier to use:

  • Magazine: 45 Round Mag
  • Optic: Aim OP-V4
  • Stock: TR Preamble
  • Underbarrel: Lockgrip Precision-40
  • Rear Grip: Casus X

4) Kastov 762

Once our favorite AR in all of Warzone, the Kastov 762 fell in viability and popularity as its recoil increased and its headshot damage decreased. It returns in Season 4 thanks to its pure damage output, but it can’t get higher than fourth right now because it’s still pretty tough to use. You’ll need to invest time into learning and controlling its kick before you can really make the most of its insane damage profile:

  • Muzzle: Eight-Point Flash Hider
  • Barrel: KAS-10 584mm Barrel
  • Optic: Aim OP-V4
  • Underbarrel: Lockgrip Precision-40
  • Mag: 40 Round Mag

3) M13B

The M13B has improved gradually since it was added back in Season One. It’s now among the best assault rifles in the game thanks to buffed damage and range. These combine with its incredible fire-rate to make a seriously powerful assault rifle, capable of outgunning any other weapon provided you can stay on target.

That’s why we’re aiming to improve its accuracy and range with our attachments. The extended mags stand out as a must have, as well as the Lockgrip. It does impact ADS and sprint to fire speeds slightly, but it’s well worth taking the hits here for the boost it gives to your accuracy:

  • Optic: Aim OP-V4
  • Underbarrel: Lockgrip Precision-40
  • Rear Grip: D37 Grip
  • Magazine: 60 Round Mag
  • Stock: Bruen R90 Factory

2) M4

The M4 is a classic of the CoD series and has been very popular in the rebooted MW series, especially in multiplayer where it’s an early unlock and all-round powerful AR. It’s not really done a lot in Warzone though – until Season 3 Reloaded and Season 4. 

For a high fire-rate AR, it’s exceptionally easy to use and performs well in a number of key areas. There’s a little bit of recoil to combat and extended mags are a must, but we’ve got both of those covered in our recommended build: 

  • Underbarrel: Lockgrip Precision-40
  • Barrel: Hightower 20″ Barrel
  • Optic: Aim-OP V4
  • Stock: Tempus P80 Strike
  • Magazine: 60 Round Mag

1) Lachmann 556

The Lachmann 556 soared in popularity across Season 3 and stays in the proverbial driving seat in Season 4. Nerfs to rivals and buffs to its damage and range have made it a monster at medium ranges; the most important area for an AR.

It also boasts strong iron sights and negligible recoil, meaning it can compete at longer ranges – even if damage is slightly lower than we’d like. We recommend attachments to boost its handling, recoil and mobility, ensuring users can outpace other AR users in terms of getting ADS:

  • Muzzle: Harbinger D20
  • Barrel: 15.9″ Lachmann Rapp Barrel
  • Underbarrel: Phase-3 Grip
  • Optic: VLK 4.0 Optic
  • Magazine: 60 Round Mag

There you have it! Those are our rankings of the top five assault rifles in Warzone Season 4 Reloaded. This list is sure to change as we approach the Season 5 and beyond, so stick with us here and check out the related Warzone content below.
