What Is Airsoft? A Complete Beginner’s Guide
Airsoft is a team sport using replica guns firing 6mm plastic BBs. How AEG, gas and HPA guns work, what games are like, and what you need to start.
Airsoft is a team sport where players eliminate each other using replica guns that fire 6mm plastic BBs. Think of it as paintball’s more realistic cousin: the guns look and handle like real firearms, the projectiles leave no paint, and players are trusted to call their own hits honestly.
It started in Japan in the 1970s, where strict firearms laws created demand for realistic replicas that were not guns. It is now played worldwide, with a US scene built around dedicated fields, weekend skirmishes, and multi-day milsim events.
How airsoft guns work
Airsoft guns fire 6mm plastic BBs, usually weighing between 0.20g and 0.32g, at velocities capped by whatever field you are playing at. There are four main ways they do it, and the difference matters enormously when you are buying your first one.
AEG — automatic electric gun
The default. A rechargeable battery drives a motor, which drives a piston through a gearbox, which pushes air behind the BB. AEGs are reliable, cheap to run, work in any weather, and fire full auto. Roughly nine out of ten players on a given field are carrying one.
If you are buying one gun to start with, buy an AEG. Everything else is a specialization.
GBB — gas blowback
Uses compressed gas — green gas, propane, or CO2 — to fire the BB and cycle a moving slide or bolt. The recoil and the slide movement feel far more like a real firearm, which is the entire appeal. The trade-offs are real: gas costs money, performance drops noticeably in cold weather, and there are more parts to maintain.
GBB pistols are extremely common as sidearms. GBB rifles are a more committed choice.
HPA — high pressure air
An external air tank feeds the gun through a line, with an inline regulator controlling pressure. HPA offers the most consistent velocity, the best trigger response, and easy field-to-field adjustment. The costs are the price of entry and the fact that you are physically tethered to a tank on your back.
Spring
Manually cocked before every shot. Cheap and simple, which makes spring pistols popular as backups, but the real reason spring matters is bolt-action sniper rifles — where a single precise shot beats volume of fire anyway.
| Type | Best for | Watch out for |
|---|---|---|
| AEG | Almost everyone, especially beginners | Battery care; gearbox wear over time |
| GBB | Realism, sidearms, pistol play | Cold weather performance; ongoing gas cost |
| HPA | Consistency and trigger response | High entry cost; tethered to a tank |
| Spring | Sniper rifles and cheap backups | One shot per cock; no full auto |
How a game of airsoft actually works
Most games run 15 to 30 minutes on a field somewhere between a warehouse and a wooded acreage. Common formats:
- Team deathmatch — eliminate the other team. The default.
- Capture the flag — self-explanatory, and still the most reliably fun format.
- Objective / domination — hold positions or complete tasks under a timer.
- Milsim — military simulation, running from a few hours to a full weekend, with limited ammunition, radio communication, roles, and sleep deprivation as a feature rather than a bug.
The honor system
This is the part that surprises newcomers most. Airsoft BBs leave no paint, so there is no objective evidence you were hit. The sport runs entirely on players calling their own hits — you feel the BB, you shout “hit,” you raise a hand or a dead rag and walk out.
It works better than it sounds. Deliberately ignoring hits is the fastest way to a bad reputation and the fastest way to get removed from a field. The honor system is genuinely part of the culture rather than a weakness in it.
Safety rules you will encounter everywhere
- Eye protection stays on inside the field. No exceptions, ever, including to wipe fog.
- Chronograph before you play. Every gun is velocity tested; over-limit guns do not go on the field.
- Minimum engagement distance. Inside a certain range you must offer a surrender — the “bang rule” — rather than shooting.
- Barrel covers off the field. Guns stay covered and on safe in the staging area.
What you need to start
The genuine minimum is smaller than most beginners expect:
- Sealed, ANSI Z87.1-rated eye protection. The one item you should never economize on. Sealed goggles rather than shooting glasses — BBs get around open frames.
- An AEG. A reliable starter rifle. Our best airsoft guns guide covers the models worth buying at each budget.
- A battery and charger, if not included. Check whether your gun takes a stick or nunchuck battery before ordering.
- BBs. 0.25g is a sensible all-round starting weight. Buy quality — cheap BBs jam guns and cost more in repairs than they save.
- Long sleeves, trousers, and gloves. Ordinary clothing is fine.
- A lower-face mask if you would rather protect your teeth.
Most fields rent guns and eye protection, which is worth doing for a first visit before you spend anything.
What it costs
A workable first setup — entry AEG, battery, goggles, BBs — generally runs somewhere in the low-to-mid hundreds of dollars, with field entry typically in the $20 to $40 range per day plus gas or ammunition. Prices move constantly across retailers, which is why we track them.
Airsoft vs paintball vs BB guns
| Airsoft | Paintball | BB / pellet guns | |
|---|---|---|---|
| Projectile | 6mm plastic, 0.20–0.40g | ~17mm gelatin, ~3g | Metal BB or pellet |
| Shot at people? | Yes, with protection | Yes, with protection | Never |
| Hit marking | Honor system | Visible paint | n/a |
| Realism | High — 1:1 replicas | Low — purpose-built markers | Varies |
| Ammo cost | Very low | Higher | Low |
The critical distinction is the third column. Metal-projectile BB and pellet guns are not airsoft, carry far more energy, and are never safe to shoot at a person. They are frequently sold beside airsoft guns and frequently confused with them.

Is airsoft legal?
Legal across the United States at the federal level, with the significant caveat that state and city rules vary widely — and a handful of places are strict enough that retailers will not ship there at all. Federal regulation requires imitation firearms to carry a blaze orange muzzle marking.
Before buying, check your local ordinance. We cover the strictest jurisdictions and why orders get cancelled in why airsoft guns won’t ship to New York, and the age rules in how old you have to be to play airsoft.
Your first game, realistically
Rent a gun. Wear long sleeves. Keep your goggles on. Call your hits generously — over-calling is invisible, under-calling is not. Ask someone experienced what the field’s engagement distance is before the first game rather than after.
Nobody expects a new player to be good, and airsoft fields are unusually welcoming to beginners who ask questions. The players who have a bad first day are almost always the ones who showed up in shorts with no eye protection and no idea what the surrender rule was.
Frequently asked questions
What is an airsoft gun?
A replica gun that fires 6mm plastic BBs at low energy, designed to be shot at other players wearing protective gear. They are powered by electric motors, compressed gas, high pressure air, or a manual spring.
Is airsoft the same as paintball?
No. Airsoft uses small plastic BBs that leave no mark and relies on players calling their own hits, while paintball uses larger gelatin balls that burst on impact. Airsoft guns are realistic replicas; paintball markers are purpose-built sports equipment.
Do airsoft guns shoot real bullets?
No. Airsoft guns fire 6mm plastic BBs and cannot chamber or fire live ammunition. They are not firearms, though they are deliberately built to look like them.
How much does it cost to start airsoft?
A basic setup of an entry-level AEG, battery, eye protection and BBs typically runs a few hundred dollars, with field entry usually $20 to $40 per day. Renting at a field first is cheaper than buying blind.
What does AEG mean in airsoft?
Automatic Electric Gun. A battery-powered motor drives a gearbox that compresses air to fire the BB. AEGs are the most common type of airsoft gun and the standard recommendation for beginners.
