The name of the game with a killer Kastov 545 loadout is to crank up the lethality factor at long range and give this assault rifle a fighting chance over its brothers and sisters. That’s the only way you’ll consistently hit the sky-high KD ratios every Warzone player needs to dominate. Otherwise, hey, you may as well not bother with the 545 and rock into Al Mazrah with one of Warzone’s SMGs.
First up, the IG-K30 406mm barrel does a great job of taming the Kastov’s recoil while cranking up the bullet velocity. This pairs nicely with the FTAC Ripper, to give the 545 seriously tight stability (you’ll definitely want Double Time in your perks for this loadout though to counter the dip in movement speeds).
Whack on your favorite optic and you’re nearly good to go. We’d suggest the Aim OP-V4, but if there’s another that tickles your pickle, go for it!
The 5.45 High Velocity ammo rounds out the build nicely, giving the Kastov the extra damage it needs for those long-range encounters. Combo that with the 60 Round Mag so you’re less likely to run out of ammo when you need it most.
Perks and equipment
Even with a loadout like this, we'd still suggest using Overkill so you've got another primary weapon to support the Kastov. You're probably better off with an SMG, something like the ISO45, that way you can still get your mid-range merk on.
Of course, that means Fast Hands is pretty essential, and as we already mentioned, you can't really go without Double Time, unless you’re happy with the dip in movement speed from those attachments.
The best perks for a Kastov 545 build are always going to focus on movement, and the same goes for your lethal and tactical equipment. As long as you've got gear that keeps you spritely, you should be onto a winner.
FAQs
What is the best AR to use in COD?
Several assault rifles perform exceptionally well in Call of Duty depending on your playstyle and preferred engagement range. The Kastov 545 and Merrick 556 are strong all-round choices due to their accuracy and versatility. The Kilo 141 and GPR 91 are also great picks for players who value stability and minimal recoil. If you prefer faster handling and mobility, the M4 and Lachmann-556 remain dependable options. Each rifle has unique characteristics, so testing a few builds to match your comfort and recoil control is recommended.
What is the best AR with no recoil?
No AR truly has zero recoil, but some come extremely close when optimised. The Kastov 545, with the right attachments (long barrel, high-velocity ammo, tight recoil mods), is known for being one of the smoothest and easiest to control ARs in current meta. Also, the GPR 91 is praised for its easy handling and low recoil, making it ideal if you want a “zero-feel” recoil experience.
What gun is the Kastov 545 based on?
The Kastov 545 is based on a real-world rifle chambered in 5.45×39mm, closely resembling the AK-105 platform. It uses an intermediate caliber to give it less recoil while maintaining a high rate of fire.
