Since 1 April 2019 a new regulation has been introduced that ensures that replicas are now measured in joules instead of fps, with BBs of at least 0.3 g instead of 0.2. Replicas have the following joule values: Bolt action sniper: 2.3 joules (499 fps with 0.2 g), DMR: 1.7 J (430 fps with 0.2 g), AEG: 1.2 J (360 fps with 0.2 g).

Velocity vs. energy chart for 6 mm Airsoft pellets. The pellet speed of spring-powered and automatic electric guns is determined in large part by the tension of the gun's main spring. Muzzle velocity limits are between 90 and 120 m/s (300 and 390 ft/s) for AEGs and 120 to 170 m/s (390–560 ft/s) for single-shot spring sniper rifles .
Before gameplay, an airsoft gun's muzzle velocity is usually checked through a chronograph and usually measured in feet per second (FPS) or joules, a measurement for kinetic energy. Some countries have a set velocity or muzzle energy restriction; guns shooting over the legal muzzle velocity can be confiscated.
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.
Airsoft is safe when played with proper protective gear. Most airsoft guns on the market are usually below 350 ft/s (110 m/s), but projectiles expelled from any type of airsoft gun can travel as slow as 65 ft/s (20 m/s) to more than 700 ft/s (210 m/s) and are capable of breaking skin at 350–400 ft/s (110–120 m/s).
Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
