A game where opposing teams use either electric, gas, or spring powered replicas of real guns, to propel a small diameter ball-bearing(BB) at the opposing team. These replicas use varied weight bbs as ammunition, with each weight giving a different effect on the range, speed, and accuracy of the shot. The replicas can be upgraded by opening it up, and changeing various parts in order to achieve the effect desired. Most fields have an FPS limit, usually 400fps for automatic and semi-automatic firing replicas, and 550fps for single-shot bolt action rifles.
Most replicas used on field are either Gas powered or electric powered.
The electric powered ones use a battery that runs a motor, that turns a set of gears, which in turn cranks back a spring, which pulls back on a piston , which then raises the amount of air in the cylinder, which is all released at once raising the pressure behind the bb in the chamber which propels the bb down the barrel, all at the pull of the trigger. The gas replicas use ozone-friendly HFC-134a(weakest) or HFC22(strongest) to propel the bb down the barrel. The gas is stored in a resivior in the magazine(ammo storage) of the replica. Spring powered replicas use manual cocking of the piston in order to raise the amount of air in the cylinder behind the bb which is all released at once, raising the amount of air pressure behind the bb propeling it foward and down the barrel.
Military style tactics and dress are often used to the advantage of the player, which is why this game is often reffered to as "Mil-Sim(military simulation). The electric powered replicas are often modeled after real rifles and submachine-guns. The Gas powered replicas are oftern modeled after handguns and small submachineguns. And the spring powered replicas are modeled after a wide varity of real weapons, due to the simplicity of thier design.
The sport was oringinated in Japan, then quickly adopted in the US as an alternative to paintball. Airsoft has a relatively small following of people as opposed to the millions who play paintball, mostly due to the fact that paintball is more "user-friendly" due to the fact that most paintball guns look nothing like real guns, unlike airsoft. Airsoft requires a great deal of responsibility, due to the fact that if you are seen in public with these replicas, you could be arrested or even shot at.
Now stop using this dictionary as a forum, and flame each other somewhere else.

A "sport" for people who are too afraid, young, or cheap to play Paintball. Airsoft involves shooting small 6mm plastic BB's out of a cheaply made (usually also plastic) Chinese made gun. Airsoft players tend to try and find reasons why Airsoft is better than Paintball, when really they are backing themselves on false claims so they can feel better about themselves. Many Airsoft players are in the 10-12 year age group. One common claim Airsoft players make is that Airsoft BB's fly much farther than Paintballs. This is a clear example of the ignorance of an Airsoft player, they do not understand that it takes a well made piece of precision engineering to launch a Paintball 150 feet accurately. While any Chinese nobody can create an Airsoft gun that easily can shoot over 200 feet.

Before the explosion of cheap Chinese Airsoft guns, an Airsoft player could expect to pay $200-$300 for an entry level gun, which is roughly the same as an entry level Paintball gun.
Person1: Hey man wanna go paintballing today? Its an awesome day for some woodsball.

person2: No way man my mom says I'm not allowed to Paintball, how about some Airsoft in my backyard instead?

Person1: Why am I still friends with you?

A poor substitute for not joining the military. Essentially its people fantasizing that their soldiers, running around in tactical gear and camo with realistic looking guns that fire BBs. Attracts frustrated special forces wannabes and war geeks who will do anything to wear camo. They go to great lengths to get the same gear that the "big boys" use.
Airsoft player: No, you didn't get me. I was behind that barrel.

SEAL team member: Sorry kid, but if I were firing my real M4 instead of this toy, you'd be dead. Steel barrels can't stop 5.56 rounds. Better luck next time...

An version of paintball created for city dwellers who either can't find a field or can't get out of town. Therefore they use smaller, less powerful guns that leave no mess.
Airsoft is a smaller no-mess version of paintball for people who can't get to a paintball field.

a game where girls don't need to play if they don't have protection 'cause it hurts like a mo fo. And it leaves bruises all over the place. It leaves welts that may even bleed. Recomended for guys only. IT SUCKS LIKE A BUTT...and don't ask 'cause there were four eggs involved...who...who knows
"hey ya'll you wanna play airsoft?"
"heck yeah hold on"
"lets not wait we'll shoot them and hide right NOW"
"OUCH stop shooting us...i think our guns broke!"

Airsoft is a game that not many people play or have even heard of. The majority of players use plastic gun replicas that fire .12g or .2g plastic ball bearings (bbs). It is possible for different weights but those are by far the most common. The people that actually play airsoft (no, I’m not talking about the ones who just like to mess around with the guns) are usually the quiet kids in JROTC that look at guns on the internet in their spare time and want to join the army so they can shoot someone with a real firearm.

Now for a quick physics lesson. Many people say "well, airsoft fields generally allow 400-550 fps and paintball fields only allow up to 300 fps.” That statement means absolutely nothing. Well as a matter of fact it does mean something; it proves that paintballs hurt much more.

This is the average force of an airsoft pellet assuming its a .2 gram bb traveling at 400 feet per second (although many airsoft guns can’t even shoot that fast).

Force = mass X acceleration

.2 grams = 0.0002 kilograms
400 feet = 121.92 meters

F = .0002 X 121.92
F = .024384 N

This is the average paintball force assuming we are using a 3.185 gram paintball (the average weight) shooting at 300 feet per second.

3.18500 grams = 0.003185 kilograms
300 feet = 91.44 meters

F = .003185 X 91.44
F = .2912364 N

So what does all this crap mean? It means that the average paintball has roughly 12x more force than an airsoft pellet traveling 100 fps faster. You can make a fair assumption based on those facts that the average paintball will hurt 12x more than a pretty fast airsoft pellet. Still don’t believe me? Well then think of it this way… what bullet would do more damage, a .22 caliber bullet or a .50 caliber bullet? Oh and airsoft pellets loose velocity much faster than paintballs, I’ll spare everyone from those equations.
Airsoft is just a sport that no one really plays. But its cheaper than paintball so it must be better, right?
