Recent Call of Duty Warzone updates, including Season 4 changes, are reshaping assault rifle metas, but the HDR sniper remains a powerhouse for battle royale success. This loadout delivers pinpoint accuracy, exceptional range, rapid fire rate, and high-capacity magazines—everything needed to outgun opponents.
Our tested HDR setup excels in long-range engagements while staying viable up close. Drawing from extensive gameplay experience across Modern Warfare and Warzone, here's the optimal HDR loadout post-Season 4 launch.

Best M4 Loadout in Call of Duty Warzone
As veteran players know, the HDR is the premier long-range sniper thanks to its high bullet velocity. Paired with the right barrel, it handles extended fights effortlessly—its weight and slower handling offset by superior ballistics.

Here's the proven HDR Warzone loadout:
Muzzle: Monolithic Suppressor
Barrel: 26.9″ HDR Pro
Laser: Tactical Laser
Optics: Variable Zoom Scope
Stock: FTAC Stalker-Scout

The Monolithic Suppressor boosts sound suppression and range, with minimal impact on mobility. Pair it with a high-magnification 8x scope for distant targets. The 26.9″ HDR Pro barrel, exclusive to the HDR sniper in Call of Duty: Modern Warfare and Warzone, maximizes velocity.

The 5mW Laser enhances hip-fire and ADS precision, activating only when aiming down sights. Ideal for quick, accurate shots. The Variable Zoom Scope suits versatile long-range play, though it slows ADS—balance with other attachments. The FTAC Stalker-Scout stock improves target acquisition and ADS speed, countering heavier setups.
For versatility, pair with Overkill and a top mid-range weapon. Pro tip: Practice recoil patterns in-game for mastery.
