Call of Duty: Modern Warfare 3’s Season 4 Reloaded update has officially launched, bringing substantial changes to the multiplayer landscape. This midseason refresh introduces two fresh armaments alongside mutation-themed maps and game modes that significantly alter strategic approaches. The comprehensive weapon rebalancing requires immediate loadout adjustments to maintain competitive performance across various engagement distances.
Understanding the new meta is crucial for players seeking to dominate matches. The update particularly emphasizes mobility and handling improvements, making weapon selection more critical than ever for success in fast-paced combat scenarios.
For those still working to obtain Season 4 Reloaded’s latest additions, detailed unlocking guides are available for both the Reclaimer 18 shotgun and the tactical sledgehammer melee weapon.

The SVA 545 assault rifle establishes itself as the premier long-range precision instrument in the current seasonal meta. Its exceptional accuracy profile makes it ideal for methodical players who prioritize shot placement over volume of fire.
This optimized configuration focuses on maximizing effective range while virtually eliminating recoil patterns. The selected attachments work synergistically to create a laser-beam weapon capable of consistent headshots at extreme distances.
Pro Tip: Combine this build with the Focus perk to maintain accuracy when taking fire, ensuring your shots land true even under pressure.

The MCW assault rifle receives a transformative upgrade through the JAK Raven conversion kit, creating a devastating SMG-hybrid that excels in close to medium-range encounters. This configuration sacrifices some long-range performance for exceptional close-quarters dominance.
This build capitalizes on the conversion kit’s mobility benefits while maintaining respectable damage output. The result is a versatile weapon capable of aggressive pushes and defensive holds alike.
Additional recommended attachments include the FSS Fortress Heavy Stock for improved sprint-to-fire timing and the 50-round drum magazine to ensure ample ammunition for multiple engagements.
Common Mistake: Many players underestimate the mobility requirements for this build – ensure you’re using Double Time or lightweight gear to maximize movement advantages.

The BP50 assault rifle specializes in rapid repositioning and flanking maneuvers, offering one of the best mobility profiles in its class. Its unique bullpup design provides handling characteristics that bridge the gap between traditional ARs and SMGs.
This configuration emphasizes ADS speed and strafe velocity, allowing players to win gunfights through superior positioning rather than pure accuracy.
Ideal attachment combinations include the Bruen Tactical Vertical Grip for movement benefits and the FSS OLE-V Laser to improve hip-fire accuracy during close-quarters emergencies.
Strategic Insight: Use this weapon on maps with multiple flanking routes like Shoot House or Rust where mobility advantages can be fully exploited.

The Superi 46 battle rifle occupies a unique position in the current meta, offering stopping power that bridges the gap between assault rifles and marksman weapons. Its two-round burst capability delivers exceptional time-to-kill when both shots connect.
This build focuses on maximizing the weapon’s damage profile while maintaining controllable recoil patterns. The result is a versatile tool effective across most engagement distances.
Key attachments include the Casus Brake muzzle for horizontal recoil control and the FTAC Matrix Rail underbarrel for improved aiming stability during sustained fire.
Advanced Technique: Master the rhythm of the two-round burst – firing at the optimal pace ensures maximum damage output without excessive recoil accumulation.

The HRM-9 submachine gun dominates in close-quarters scenarios with its exceptional rate of fire and minimal ADS requirements. This weapon excels in aggressive playstyles where reaction time determines engagement outcomes.
This configuration prioritizes sprint-to-fire speed and hip-fire accuracy, allowing players to maintain offensive pressure without sacrificing defensive capabilities.
Recommended modifications include the DR-6 Handstop underbarrel for movement benefits and the 50-round mag to handle multiple opponents during pushes.
Optimization Tip: Pair this SMG with a longer-range secondary like the BF6 Weapons Unlock to cover all engagement distances effectively.

The Kar98K sniper rifle returns as the definitive choice for players who value precision over volume. Its classic bolt-action mechanism delivers satisfying one-shot kills to the upper torso and head.
This precision-focused build minimizes scope sway and maximizes bullet velocity, creating a weapon capable of consistent long-range domination. The configuration particularly shines in objective-based modes where holding sightlines determines match outcomes.
Essential attachments include the FSS Osprey suppressor for remaining off radar and the ZLR Asp King barrel for improved damage range and bullet velocity.
Quickscoping Strategy: While primarily a long-range weapon, the Kar98K can be effective in mid-range when mastering the timing between scope-in and shot release.

The Renetti pistol serves as an exceptional secondary weapon that can save your life when primary ammunition runs dry. Its burst-fire capability offers surprising stopping power in close-quarters emergencies.
This sidearm configuration focuses on fast swap speed and reliable damage output, ensuring you’re never completely defenseless during reloads or when caught off guard.
Recommended modifications include the FTAC SATUS CS-3 grip for improved handling and the 21-round magazine to handle multiple threats without immediate reloading.
Tactical Advantage: Equip the Renetti with Akimbo for devastating close-range damage, though this requires sacrificing accuracy at longer distances.

The Reclaimer 18 shotgun represents Season 4 Reloaded’s most powerful new addition, offering devastating close-range stopping power that can eliminate multiple opponents with single well-placed shots. Its semi-automatic fire rate allows for rapid follow-up shots when initial blasts don’t secure kills.
This configuration maximizes the weapon’s damage potential while ensuring reasonable mobility for aggressive close-quarters play. The build particularly excels in tight indoor environments where engagement distances rarely exceed 10 meters.
Optimal attachments include the XRK Edge Undermounted barrel for improved damage range and the Bruen Counter-Ops stock for better handling during movement.
Unlocking Insight: The Reclaimer 18 requires completing specific in-game challenges that typically involve shotgun eliminations or objective play – expect to spend 2-3 hours focused on these requirements.
