Look Out, Paintball -- Here Comes Airsoft
When playing paintball just isn't enough
Airsoft Guns started in Japan, and now is making its way onto paintball fields in the U.S.
Don't let the name "Airsoft Gun" fool you. There is no "soft" when you're hit by an Airsoft BB. Morgan Evans, 22, of Marshall says: "If you don't mind getting shot, it's the sport for you. However, if you mind BB's flying at you, then maybe you want to stick with the X-box or the PlayStation 2."
Most Airsoft guns are spring, gas, and electric powered and can shoot their rounds at 150 - 307 feet per second. Airsoft Guns can sell for as little as $5.00 and as much as $1, 200.
Ammunition is cheaper than paintball. The cost of 2, 000 rounds of paintballs is about $70; 2, 200 Airsoft BB's cost about $14.
Before anyone can play in a Wisconsin Airsoft Association game, players under the age of 18 must complete basic Airsoft training. During the one-day training course, players learn about safety and equipment and are given a marksmanship evaluation.
Unlike paintballs, which make a mark, Airsoft employs an honor system: When a player is hit, he calls him- or herself out. Not doing this can get you banned from future play.
Airsoft guns shoot 0.2 g BBs at velocities from 100 ft/s (30 m/s) for a low-end spring pistol, to 550 ft/s (170 m/s) and beyond for heavily-upgraded customized sniper rifles. Most non-upgraded AEG's using the Tokyo Marui system are in the middle, producing velocities from 270 to 300 ft/s (80 to 90 m/s), but upgrades to the internal components can increase the pellet velocity significantly.
Hop-up & Bernoulli's principle Bernoulli's principle is a physical law that says that if a pellet is given a backspin an overpressure is formed under the bullet and an under pressure is formed on the top of the bullet. These pressures affect the bullet as on an airplanes wings a lift is formed. The bullet is sucked upwards. If the force caused by the backspin is equal to the effect of gravitation the bullet will fall slower and have a flatter trajectory, which gives the pellet longer range. In Airsoft guns this is often implemented as a rubber piece at the rear of the barrel that is thicker at the top of the barrel than the bottom.
