Tune A Paintball Gun

Paintball is an extreme sport that pits teams of players against one another in simulated combat situations. Balls of gelatinous paint are used instead of live ammunition in specially crafted paintball guns, commonly known as “markers”, that are used to fire upon opposing combatants. Paintball guns use compressed air to launch the paintballs at high velocities. Properly tuning a paintball gun increases its longevity as well as its accuracy and reliability on the field.


1. Disengage and remove your air canister. Safety is paramount and the gun must be unable to fire during the tuning process.

2. Clean the marker using a sponge and warm water. The water dissolves any paintballs lodged in the barrel or paint that has splattered on the outside of the weapon.

3. Dry the gun with a soft cotton towel. All water should be removed in order to properly lubricate the marker.

4. Apply three drops of paintball gun oil to the moving parts of the weapon. Proper lubrication ensures correct timing for your shots and helps prevent jams.

5. Check the O-rings for damage. Damaged seals can cause dangerous situations if the compressed air tank releases its contents toward a user. These should be replaced immediately.

6. Place a paper target at chest level and approximately 20 to 50 yards from your firing location. If you are shooting a sniper rifle, longer ranges should be used. Use shorter distances for assault rifles or other close combat weaponry.

7. Set your chronograph to measure the speed of the paintballs. Safe paintball firing speeds are between 275 and 300 feet per second.

8. Attach your paintball air canister.

9. Adjust the scope on the weapon, or align the sights, to the center of the target.

10. Fire three shots towards your target. Take note of which shots hit the correct area. The spread should completely cover the targeted area.

11. Make any further adjustments to the scope or regulator as necessary to attain a perfect hit and speed. Use the sliding wheels of your scope and the paintball gun or tank’s regulator settings as directed by the manufacturer. This process varies by marker.
