Here's how to build the ultimate XM4 and Tanto 22 classes for multiplayer. U4GM provides a safe and cheap black ops 6 bot lobby service, allowing you to quickly unlock and upgrade weapons.

 XM4 Setup (Post-Buff)  
The XM4 saw a slight damage adjustment but gained significant range buffs:  
- Damage Range: Increased to 40.6m at max damage.  
- Headshot Multiplier: From 1.15 to 1.25.

Attachments:  
- Muzzle: Suppressor – Reduces recoil visibility and keeps you off the radar.  
- Barrel: Reinforced Barrel – Increases bullet velocity and damage range.  
- Underbarrel: Ranger Foregrip – Enhances movement and recoil control.  
- Magazine: Extended Mag 2 – Prolonged engagements with 50+ rounds.

This configuration balances precision and stealth, making it a top-tier AR for all ranges.

 Tanto 22 Setup (Hidden Gem)  
The Tanto 22 received an overlooked buff in mobility and range capabilities.  
- Fire Mod: Rapid Fire – Boosts fire rate for quick kills.  

Attachments:  
- Muzzle: Ported Compensator – Balances rapid fire recoil.  
- Barrel: Reinforced Barrel – Restores bullet velocity and range lost from Rapid Fire.  
- Underbarrel: Ranger Foregrip – Adds stability for high-speed encounters.  
- Magazine: Extended Mag 2 – Keeps you engaged without frequent reloads.

This build transforms the Tanto 22 into a versatile weapon that bridges the gap between SMG mobility and AR firepower.
