How to Chrono a Paintball Gun: FPS Limits and Adjustment
How do you chrono a paintball gun? Chronographing a paintball gun means measuring the velocity of a fired paintball in feet per second (FPS) and adjusting the marker’s regulator or velocity screw to stay under the field’s legal limit. Most fields require markers to shoot at or below 280 FPS, and chrono testing happens before every game session and any time a player changes paint or adjusts the marker. Legal Velocity Limits League or Setting FPS Limit Most US recreational fields 280 FPS NXL tournament play 285 FPS Most European fields 280 FPS Indoor fields 250–280 FPS (varies) Low-impact .50 cal fields 250 FPS Youth or family fields 230–250 FPS The 280 FPS standard exists because tests in the 1980s identified velocities above 300 FPS as the threshold where standard paintballs can break skin or cause eye injury through a damaged lens. Fields chrono at 280 to leave a 20 FPS safety margin. For more on safety standards, see is paintball safe. ...
