Meta Kastov 545 Attachments in Warzone 2
The FTAC Castle Comp is a great muzzle attachment for reducing recoil on the Kastov 545, but there are plenty of great choices. You can also use the Sakin-Tread 40 if you prefer less vertical recoil or the FJX Fulcrum Pro for balanced recoil control!
The IG-K30 406MM barrel is perfect for our long-range Kastov 545 build. This is thanks to the 9% reduction in vertical and horizontal recoil it provides, alongside additional damage range and bullet velocity.
We have gone for the Aim OP-V4, thanks to its low visual recoil, but feel free to choose your favorite optic!
High bullet velocity is always helpful for long-range gunfights, and there is no better attachment to increase this than the 5.45 High Velocity ammunition!
Finally, every gun needs an extended magazine. The 60 Round Mag is the largest available for the Kastov 545, so that’s what we’ve gone for!
