The Haunting Season 6 is the climactic final season for Call of Duty: Modern Warfare 3, bringing a variety of Halloween-themed content drops to both Multiplayer and Warzone. In this season, players can dive into multiple 6v6 Shipment variants or battle it out in Warzone's Purgatory mode. Alongside unique maps and modes, Season 6 introduces two weapons via the Battle Pass.

Call Of Duty - Modern Warfare 3: 6 Best Cosmetics In Season 6

With the release of Modern Warfare 3's Season 6, players have a variety of new cosmetics to get their hands on.

While the DTIR 30-06 is quickly becoming a meta option in both games, the Kastov LSW is also a solid choice. This Light Machine Gun boasts the best accuracy in its class when used in tac stance — and a fast fire rate for high TTK. With the best loadout, however, the Kastov LSW can be made even better.

How To Unlock The Kastov LSW

The Kastov LSW is one of two weapons available in the Season 6 Battle Pass. To acquire it, players must first reach Sector 9 by progressing through previous Sectors with Battle Pass Tokens. The quickest way to get there is by claiming all the rewards in Sectors 1, 3, and then either 5 or 8. Once done, players need to claim all rewards in Sector 9, before using one last Battle Pass Token to unlock the Kastov LSW.

For players looking to skip the grind, purchasing the Season 6 Battle Pass and using its 20 Tier Skips is a great alternative. However, doing so will cost 2,400 COD Points.

The Haunting Season 6 is set to end with the debut of Black Ops 6 Season 1, and when it does, the Kastov LSW should move over to the Armory Unlock section for those who have not unlocked it.

This first build for the Kastov LSW is designed with Core Multiplayer in mind. The attachments highlighted below aim to improve the weapon's recoil while maintaining baseline levels of mobility and handling.

  • JAK Glassless Optic (Optic)
  • Spetsnaz S15 Stock (Stock)

Best Equipment For The Kastov LSW

While the Equipment package below includes many popular choices, some underrated picks have also been added, each complementing the Kastov LSW quite nicely. The benefits of the highlighted Equipment items include a boost in movement speed — perfect for a slow-handling LMG — the ability to resupply ammunition from fallen operators, improved reload speeds, and increased resistance to explosives and enemy fire.

  • Infantry Vest (Vest)
  • Scavenger Gloves (Gloves)
  • Lightweight Boots (Boots)
  • Mag Holster (Gear)
  • EOD Padding (Gear)

Secondary Recommendations For The Kastov LSW

The Kastov LSW is definitely a top-tier Light Machine Gun thanks to its improved handling, and while it has a faster reload compared to most other weapons in its category, players may still find themselves caught under fire before being able to reload. This is where a great Handgun comes in handy, and the top option for Season 6 so far is the WSP Stinger. Both the COR-45 and Renetti follow close behind, as each offers solid damage per shot.

Best Kastov LSW Loadout For Warzone

This second build for the Kastov LSW is ideal for Warzone Battle Royale. While it may not make the weapon one of the best options in the game, the attachments listed below do an excellent job of reducing the high weapon kick and recoil of the Kastov LSW, while also boosting damage range and bullet velocity without negatively affecting mobility. Although handling takes a hit — especially with aim-down-sight and sprint-to-fire speed — bringing the weapon up and firing from a distance hasn't been hindered too much.

  • Quartermaster Suppressor (Muzzle)
  • Elevator D20 Long Barrel (Barrel)
  • Paracord Grip (Underbarrel)
  • JAK Glassless Optic (Optic)
  • Spetsnaz S15 Stock (Stock)

Best Perk Package For The Kastov LSW

This next Perk Package is a solid option for the Kastov LSW. While some attributes from the previous Multiplayer package — such as improved mobility and increased reload speeds — have been carried over, the Perks below also introduce Warzone-exclusive benefits. These include making all armored vests function as Tempered Vests and providing a visual indicator showing the direction of enemies once the player has been spotted out of view.

  • Double Time (Perk 1)
  • Sleight of Hand (Perk 2)
  • Tempered (Perk 3)
  • High Altert (Perk 4)

Secondary Recommendations For The Kastov LSW

The Kastov LSW is a solid fast-firing Light Machine Gun that has the potential to shred opponents at medium range. However, following the trend of other popular LMG loadouts, bringing a solid Submachine Gun is bound to keep players covered should enemies get too close. Some of the top options for the SMG category for Season 6 include the Staic-HV, the Striker 9, the FJX Horus, and the Striker.
