airsoft guns use plastic pellets, usually 6mm, to simulate the firing of real firearms. They can be used in various games, such as Team Deathmatch, Capture the Flag and King of the Hill, to test a player’s skills and tactics. The game also promotes honesty and good sportsmanship, as players will be punished if they are caught cheating or breaking the rules. It is a social hobby that attracts people of all ages, and is equally popular with males and females, and with all levels of ability.
Airsoft gun types vary in size and power, from simple spring models to fully automatic electric guns. Some manufacturers add extra features, such as scopes and lasers to improve accuracy, although these can be expensive for beginners. They are often powered by nickel-metal hydride (NiMH) batteries of varying voltages and milliampere-hour ratings. However, lithium polymer (Li-Po) batteries are increasingly being used because they last longer and can be charged more frequently without suffering from voltage depression.
Most spring-powered guns are equipped with a “hop-up” device to increase the effective range of shots. This works by adding backspin to the pellets, causing them to fly upward in a counteraction against gravity. This is accomplished by a small rubber nub that protrudes into the barrel through a hole and catches the top of each bullet as it passes by. The nub can be adjusted to change the amount of backspin applied.
Some airsoft guns are powered by propane gas. This is an inexpensive alternative to CO2, and it can be stored in a hand-held tank for easy refills at local fill stations. Many users prefer green gas, which is propane with a little silicone oil added. This lubricates the gun as it is fired, making it much cheaper than propane alone.
