Change The Velocity On An Ion Paintball Marker

With more than 5 million U.S. users each year, the Smart Parts Ion paintball marker has been a popular entry-level paintball marker since its introduction. It offers a low price and many features found in higher-end competitive paintball markers. Chronographing the Ion is a straightforward activity with the right tools and knowledge. You should chronograph the Ion marker every day you play paintball.


Change the Velocity on an Ion Marker

1. Most fields require the velocity to be less than 300 feet per second (fps), but some require velocities as low as 260 fps. Check with the owner of your local field or league for specific requirements. In a safe and approved area, fire your Ion over the chronograph to measure the velocity.

2. Locate the nut at the bottom of the vertical regulator. This is where you will make any necessary adjustments to the velocity of the marker. If you need to decrease your marker’s velocity, use the 5/8-inch or adjustable wrench to turn this nut counter-clockwise. If you need to increase your marker’s velocity, turn this nut clockwise.

3. Remember to keep an eye on the marker’s pressure gauge to ensure that it never exceeds the Ion’s operating limit of 200 pounds per square inch (psi).

4. After every adjustment, fire three to four clearing shots before again measuring the marker’s velocity by firing over the chronograph.

5. Repeat this process, making a series of adjustments and measurements, until your marker is firing consistently within the velocity limits specified by the field at which you are playing.

6. If you can’t get your marker to fire at a consistent velocity, or you can’t get it within the velocity limits specified by your field, there are a few things you can do before seeking help from a certified technician. Check your paint to barrel match. If the paint is much smaller than the barrel, air will escape around the ball and cause inconsistency in velocity. Clean and lube the marker. If airflow is obstructed or if the marker isn’t properly lubricated, it cannot function correctly. If you properly maintain your marker it will serve you well for a long time to come. Check your dwell. If your dwell setting is too high or too low, it can cause velocity problems. Check your owner’s manual for instructions on setting the dwell back to the factory recommended setting. Check all your fittings and o-rings. If an o-ring wears out and cannot maintain a seal, it can negatively impact the performance of your marker. The Ion can also have problems if hoses or fittings are leaking or not properly seated.
