The Anti-materiel Rifle is a craftable post-Moon Lord gun. It always fires a high-damage High Velocity Bullet, regardless of the used bullet. If the first bullet critically strikes an enemy, a second swarm of bullets will fly towards the enemy's position from the left side of the screen regardless if the enemy died or not. Holding right click will use its zoom ability, which scrolls the viewing area of the screen in the direction of the cursor in a fashion similar to the Sniper Rifle.

This weapon's bullets inflict the Marked debuff onto enemies, decreasing their damage reduction by 50%; in addition, it will also remove 50 defense on hit if the enemy has more than 50 defense.

The Anti-materiel Rifle also has a rare item variant called the Skullmasher that drops from The Devourer of Gods.

Its best modifier is Unreal. Rapid may be preferred for a higher DPS, as the Anti-materiel Rifle fires extremely slowly. Ruthless may also be preferred for a large damage boost, as the Anti-materiel Rifle's base damage is extremely high.
