Best Modern Warfare 2 Kastov 545 loadout: The best Kastov 545 class setup and attachments

Here's the best Kastov 545 loadout in Modern Warfare 2

Looking for the best Kastov 545 loadout in Modern Warfare 2? The Kastov 545 is very similar to its close relative in Call Of Duty: Modern Warfare 2, the Kastov-74U. The crucial difference is that it trades in a bit of damage for increased range and lower recoil. While this isn't the recipe for a top-of-the-meta rifle, it's nonetheless a great base on which to build a strong Assault Rifle loadout.

In this guide we'll walk you through the attachments, equipment, and perks you'll need to put together the best possible Kastov 545 loadout and class setup in Modern Warfare 2. We'll also explain our reasoning behind picking each of these attachments and other tools below. So let's get started!

Despite our best efforts, the Kastov 545 is never going to compete with SMGs at close-range. That's why with this loadout we've chosen to lean on the Kastov's low recoil, creating a sturdy and reliable high-capacity Assault Rifle that allows for swift transfers so you can mow down multiple enemies in quick succession.

  • Barrel: KAS-7 406MM
  • Magazine: 45 Round Mag
  • Stock: Kastov-Rama
  • Optic: Cronen Mini Pro

After testing various Muzzle attachments we decided the Silentfire XG6 hits the sweet spot in terms of extending the Kastov 545's effective range and lowering its recoil, without hitting the gun's handling stats too hard. We've combined it here with the KAS-7 406MM Barrel, a heavy barrel that helps increase bullet velocity and reduce recoil even further.

30 Round Mags are often enough for most Assault Rifles, but here we really like the extended capacity granted by the 45 Round Mag on the Kastov 545, because its reload speed isn't excellent, and this ensures you can keep shooting for longer and win fights more consistently.

We've slowed down the gun considerably with these three attachments, so it's now time to add the Kastov-Rama Stock, which boosts Sprint Speed and Aim Walking Speed back up to acceptable levels. Finally, add your choice of low-zoom optic. The Cronen Mini Pro is always a good pick here.

Best Kastov 545 loadout secondary weapon

Despite its increased effective range over the Kastov-74U, the Kastov 545 isn't the kind of Assault Rifle you should expect to perform well at long ranges. Therefore, the ideal pairing for the Kastov 545 is a good Sniper Rifle. Our personal choice here is the SP-X 80, a fantastic lightweight rifle ideal for quickscoping, and the best Sniper Rifle in Modern Warfare 2 right now in our opinion.

Best Kastov 545 class setup: Perks and Equipment

Picking perks for this Kastov 545 build is fairly straightforward. First, pick up Overkill so you can equip the SP-X 80 in your secondary weapon slot. Next up you should speed up your mobility with the double-whammy of Double Time and Fast Hands, as this fits perfectly with the aggressive playstyle of the Kastov 545.

The ideal Ultimate Perk in this case is likely Ghost, which renders you invisible to UAVs and allows you to keep running-and-gunning even with the most popular Killstreak flying overhead. As for equipment, pick up some Thermite for quick kills and zoning areas, and a Flashbang for ensuring kills as you turn corners or enter rooms, and you'll find yourself earning kills much more easily with the Kastov 545.

If you've followed the above attachment and equipment recommendations to the letter, you should now have a Kastov 545 class setup with enormous potential for such an off-meta rifle.
