How to set velocity on tippnan 98 custom - Tippmann 98 Custom Act Paintball Gun

There is a velocity adjuster on the left side of the body, just below and to the right of the "N" in "TIPPMANN."

In order to adjust the velocity you need to be in a place where it is safe and legal to fire your marker (paintball field, with all bystanders protected by netting or paintball goggles.) You will need a chronograph and a 3/16-inch hex wrench.

The adjuster is a screw that blocks the gas flow from the valve to the bolt. If you screw it in (clockwise) it blocks more of the gas, so your velocity goes down. If you screw it out (anti-clockwise) it blocks less gas, so the velocity goes up.

Just take a shot over the chronograph to check your velocity, adjust and check again until you get it where you want it. Most paintball fields limit velocity to 285 feet per second. Never go above 300 feet per second, as velocities above that are unsafe (beyond paintball goggle ratings and can cause damage and infection on skin due to the heavy impact.)

It is important to test and adjust the velocity before each day of play, and even multiple times during the day as weather changes, because it is affected by temperature.
