How Big Is an Indoor Airsoft Arena? Airsoft Guns and Safety

by

Most North American indoor fields allow 350 FPS (feet per second) maximums. Outdoor limits typically range 450 to 550 FPS with minimum engagement distances for safety.

Material Strength

Aluminum alloy 6061’s tensile strength is 290MPa. Mild steel’s is 370MPa. Impact strength measures physical toughness by fracture resistance under impact or shock. Airsoft BBs are usually made from non-biodegradable acrylonitrile butadiene styrene (ABS).

Gameplay and Equipment

As ammunition sizes differ considerably, airsoft strikes hurt less than paintball hits. Paintballs have a higher impact rate. So professional paintballers wear lightweight armor and full-face protection. Airsoft guns almost always sting when hitting exposed skin. Sniper rifles have better range, accuracy, consistency and higher FPS limits, often 500 FPS with a 0.2g BB.

  • 250 – 350 FPS airsoft replicas may cause anything from a flick to a sting. The pain dissipates in seconds.
  • 350 – 450 FPS may hurt, welt or bruise.
  • Except for snipers and pistols, airsoft weapons have a 400 FPS maximum using .20 BBs.
  • Heavier BBs might be used.
  • The maximum firing rate is 20 balls per second. More causes overheating.
  • Airsoft guns usually shoot 100-250 FPS.
  • Professionals use 350-400 FPS equipment.
  • Practice and technology increase FPS.

FPS measures your BB’s speed – its range per air second. So average airsoft FPS limits are 200-400. But places and laws change this. Four factors acknowledge FPS limits! Indoors, FPS limits change. With 80-100 foot ranges, a 280-FPS marker reaches its target in one-third of a second. A 400-FPS airsoft gun can cover 100 feet. Pistols with the same FPS cover 50 feet.

The field maximum is 400 FPS with 20g BBs. Some semi-automatics (like SVDs) can reach 500 FPS and 2.31 joule maximums, with a 100’ minimum engagement distance. Airsoft M4 brands like Tokyo Marui have licensed Colt M4 CQBR models. Their NGRS series features recoil shock and realistic blowback.

In the U.S., safe airsoft FPS is under 400 FPS outdoors and under 350 FPS indoors.

Performance and Regulations

A 400 FPS BB gun shoots 100 feet. Pistols reach 50 feet at the same FPS.
