Best Kastov-74U loadout in Warzone 2

Here's the best Kastov-74U loadout in Warzone 2:

  • Barrel: Shorttac 330mm (Unlock at Kastov-74U lvl 16)
  • Underbarrel: Phase-3 Grip (Unlock at Vaznev-9K lvl 9)
  • Ammunition: 5.45 High Velocity (Unlock at Kastov 545 lvl 15)
  • Magazine: 45 Round Mag (Unlock at M4 lvl 5)
  • Optic: Cronen Mini Pro (Unlock at Expedite 12 lvl 7)

Rather than doing anything drastic like collapsing the stock, we've taken advantage of the Kastov-74U's naturally high handling speeds to balance out a powerful selection of the best Kastov-74U attachments for lowering recoil, extending the magazine, and increasing bullet velocity. With this Kastov-74U loadout, you'll be able to keep your crosshair on target while you mow down whole enemy teams in a startlingly short space of time.

Our Kastov-74U build aims to lower recoil and increase bullet velocity, so that you can beam baddies with ease.

As always, let's start with the Barrel attachment. The Shorttac 330mm is a fairly lightweight Barrel mod which serves to lower recoil (a much needed trait for any good Kastov-74U build) while also extending bullet velocity. We've then ramped that bullet velocity to the max with the 5.45 High Velocity Ammunition, to help boost the gun's effectiveness at range and keep it feeling as responsive as possible.

The 45 Round Mag slows the gun down a bit, but it's worth it for the extra magazine capacity, which is great for dealing with multiple threats in quick succession. You'll be doing a lot of that in Warzone 2.

Next we've lowered the recoil further with the Phase-3 Grip - one of our favourite Underbarrel attachments and one which also boosts hipfire accuracy for messy close-quarters circumstances. Finally, add your choice of Warzone 2 Optics attachment. We've opted here for the Cronen Mini Pro for its clean, no-nonsense sight.

You'll find that with the above attachments in place, the Kastov-74U's main downside - its high recoil - will be very significantly diminished. This allows you to stay on target and mow down enemies with the Kastov-74U's extremely high DPS. Remember that you can potentially push that control and accuracy even further with weapon tuning. It lacks some of the speed of its default self, but when compared to even some of the best Assault Rifles in Warzone 2 it's still a very speedy gun.

Given the Kastov-74U's fairly close range for an Assault Rifle, you'd best pair it with a long-ranged alternative. The best Sniper Rifles reign supreme in Warzone 2's massive open environments, so we'd recommend you pick either the Signal 50 (faster-firing) or a Victus XMR (harder-hitting) depending on your sharpshooting preferences.

Best Kastov-74U class setup: Perks and Equipment

If you're looking to get a loadout drop in Warzone 2 and want some perks ready to go, then the Specter perk package (Ghost, Double Time, Tracker, Spotter) should suit this Kastov-74U build perfectly. Ghost is almost an essential perk, allowing you to remain undetected by enemy UAVs. That makes it much easier to survive when they start popping in the late game, and might be the difference between an unexpected death near the end and an easy win.

Tracker is excellent for making an aggressive push when you are in the final circle, revealing enemy footsteps on the ground as they run by. You can use this to sneak after them and deliver an easy bullet into the back of their skull, bagging you an extra late-game kill. If you're worried about losing them, Double Time's extra tac sprint duration should help you stay hot on their heels. Fortunately, Spotter will keep you covered from enemy equipment, highlighting claymores and other pesky gear that might be lurking behind doors and by windows.

That doesn't mean you can't catch baddies off guard with your own gear, though. Consider equipping a C4 charge in your lethal slot, so that you can quickly toss it into a crowded room and potentially snag a simple squad wipe. For your tactical, use the Heartbeat Sensor to detect the amount of enemies lurking nearby, so that you can prepare before barging into a room.

If you've followed the above advice, you should now be ready to call upon the power of one of the very best guns in Warzone 2 when you bring the Kastov-74U into your next foray through Al Mazrah.
