by

Airsoft FPS Limits

  • Assault rifles: 400 feet per second (fps)
  • Semi-automatic sniper rifles: 500 fps and 15 m engagement distance
  • Mandatory secondary up to 400 fps
  • Most indoor North American fields allow 350 FPS maximum
  • Outdoor limits typically 450 to 550 FPS with minimum engagement distances
  • Site FPS limit for full auto firing weapons is 350 FPS
  • Snipers semi or bolt action only, may be 500 FPS maximum
  • Pistols considered backup, restricted to 350 FPS
  • FPS Limits strictly enforced, all guns chronographed
  • Snipers not allowed full auto or semi-automatic electronic guns

Airsoft Gun Regulations

  • Airsoft BBs used as ammunition
  • Airsoft replica weapons absolutely cannot be converted into real weapons
  • Parts not remotely the same, original parts cannot fit
  • Due to US law, every airsoft gun comes with an orange tip

Airsoft FPS and Range

  • Range plays a big factor
  • Rifles and snipers operate around 400–500 FPS with 0.25g bbs
  • Heavier BBs drop slower
  • High-end guns effective range 300 feet on field

Additional Guidelines

  • Under 18 cannot buy airsoft guns
  • Must retain buyer documentation for 5 years
  • Orange/red tip required to differentiate from firearms
  • Still strong restrictions on importing accessories like sights, magazines—require permit and taxes

Conclusion

  • Manufacturers make products realistic
  • Judge if need highest or average good enough
  • Weather affects FPS minimally
