Why this Kastov 762 build works

The Kastov's problem is recoil, so this build is all about control and handling. The angled grip, rear grip and stock tame the kick, the short barrel keeps it snappy so it plays well on the run, and the laser speeds up your aim. You get the Kastov's heavy damage without fighting the gun.

Best class and perks for the Kastov 762

Run the universal class: Perk 1 Ninja (Level 20), Perk 2 Fast Hands (Level 12), Perk 3 Battle Hardened (Level 28), with a Semtex lethal and a Flashbang tactical. Battle Hardened unlocks at level 28, so use Blood Rush or Scavenger until then.

Remember: it is a beta

Expect Activision to buff and nerf guns, add weapons and drop new maps before the October 23 launch, so the AR meta can shift. Treat this as the best Kastov 762 build right now.

Unlock the attachments fast

The Kastov 762 unlocks later in the beta, a grind on the short clock. MW4 Beta Gun Leveling maxes the Kastov and unlocks every attachment for you, MW4 Beta Bot Lobbies let you level fast yourself, and our guide on leveling guns fast covers the free methods.
