Its firing mechanism can be operated by a pressurized gas (CO 2, propane, butane …), an electric motor or a spring (spring) manually rose.
Airsoft is a game using replicas of firearms propelling plastic balls of 6 or 8 mm and a mass varying between 0.10 gram and 0.43 gram. The “power” (kinetic energy) can vary between 0.1 and 2 joules (power limit by French legislation) according to the replica and the ambient temperature (for replica gas or CO2) For propulsion replicas can use compressed air, pressurized gas or CO2, batteries, or, for replicas called “spring”, a simple spring (manual reloading and arming). A replica airsoft is over-the-counter to any major person. Past 2 joules a replica weapon becomes a weapon in the eyes of the law.
