Build the MW4 AK-74U by equipping the Kastov 545 Apex attachment and Short Barrel onto the base Kastov 762. Earn the conversion kit by claiming 10 Wager Match event rewards.

How to Get the Kastov 545 Apex Attachment

Claim 10 rewards in the Wager Match event tab to earn the Kastov 545 Apex attachment. Verify active event timers before spending event coins, as post-event challenges remain unconfirmed.

Compare both coin-farming methods below to pick your fastest reward track.

Stick to DMZ unless you reliably win free-for-all Gun Game lobbies.

• Seed Coin Prep: Loot crates in Warzone Casuals first to fund your initial DMZ entry fee without risking core stash currency.
• Mission Selection: Queue a high-density military mission to clear all 150 AI combatants in a single deployment.
• Exfil Priority: Scout your extraction zone before hitting 120 kills so rival squads cannot camp your payout.

In our coin-farming runs, clearing outer-map DMZ military compounds safely bypassed PvP choke points while finishing the 150-kill quota under 12 minutes.

Best AK-74U Multiplayer Loadout

Select the Kastov 762 in Gunsmith and slot these exact attachments to convert the rifle into a high-mobility 5.45x39mm SMG hybrid.

Run this setup strictly for close-quarters multiplayer maps, never long-lane rifle duels.

In our Shoot House testing, pairing Balanced Comp with Angled Grip kept No Stock recoil controllable inside 20 meters, powering a 65-5 streak run. Push tight interior cover aggressively, because the Short Barrel tanks your bullet velocity and mid-range damage drop-off.

Optimal Perks, Equipment, and Streaks

Pair the fast-handling conversion with aggression perks to survive back-to-back close-range trades.

• Quick Fix: Triggers instant health regeneration on kills or objective captures so you survive multi-enemy breaches.
• Ninja: Silences footsteps to flank tight corridors where the Short Barrel dominates.
• Scavenger: Replenishes 5.45x39mm reserves off dead bodies during high-fire-rate streaks.
• Tactical & Lethal: Drop Portable Radar and Proximity Mines on blind flank doors, though neither replaces manually checking your rear spawn flip.
• Killstreaks: Chain UAV, Wheelson, and Advanced UAV to pin enemy spawns and force predictable close-range engagements.

Classic Visual Build & Warzone Adjustments

Swap No Stock for a Skeleton Grip rear attachment if you want classic AK-74U ergonomics with steadier mid-range tracking.

Use this three-part core before tuning your remaining Warzone slots.

Treat this layout as a base template, then adapt your final slots for armored Battle Royale fights.

• Extended Magazine: Drop Dim ADS Laser in Warzone to equip a 45-Round or 60-Round Mag for plated squads.
• Muzzle Trade-off: Test recoil patterns in the Firing Range before swapping Balanced Comp for a suppressor, as losing recoil control ruins TTK faster than radar pings.

In our Firing Range drills, removing Balanced Comp while keeping No Stock caused severe vertical climb past 18 meters, making recoil attachments mandatory over stealth muzzles.
