Airsoft Shotgun Guide: Spring, Gas and Tri-Shot Explained

An airsoft shotgun is the simplest gun on the field. Most are spring-powered: you pump once and it fires, and a tri-shot sends three BBs down three barrels at the same time. This guide explains how spring, gas, shell-ejecting and electric shotguns work, how shells and reloading go, why shotguns do so well at British indoor sites and what to look for when you buy one, new or used.

In short

  • Most airsoft shotguns are spring-powered. You pump, it fires. No battery, no gas, very little to go wrong.
  • Tri-shot means three BBs per pump. Three thin barrels sit inside the one you see. A shell holds 30 BBs, the 6 mm plastic balls airsoft guns fire: ten shots.
  • Gas adds speed and realism. A lighter pump and three or six BBs per shot, paid for in gas, upkeep and trouble on cold days.
  • It is a close-range gun. Excellent in buildings, where a rifle's reach counts for little. In woodland you have to get close.
  • In the UK: a RIF or a two-tone. A realistic-looking shotgun is only sold where the seller can show you skirmish; anyone of 18 or over can buy a brightly coloured two-tone.

Why play with a shotgun

An airsoft shotgun does one thing well: it puts BBs on a target a few steps away, every time, in any weather. With most airsoft shotguns you pull the fore-end back and push it forward, the pump, and the gun is cocked and loaded. There is no battery to charge and no gas to run out.

That is why shotguns are popular at British sites for CQB, close-quarters play in buildings: they sit under every power limit and ask for almost no maintenance. A pump-action is also one of the few cheap airsoft guns that hold their own in a real game, which makes it a fair answer for anyone searching for a first BB gun rifle on a small budget.

Five kinds of airsoft shotgun

Spring, one barrel

The cheapest kind: one BB per pump, fed from a small magazine or a tube, not from shells. Fine for trying a game day, soon outgrown.

Spring tri-shot

The standard. Three BBs per pump from a shell you push in underneath. Simple, tough and good indoors: the kind to buy first.

Gas, three or six BBs

Gas does the pushing, so the pump is light and quick, and some models let you choose three or six BBs per shot. Needs gas, which we cannot ship to the UK.

Shell-ejecting

Every shell holds a few BBs and flies out when you pump. As close to the real thing as airsoft gets, and you spend the day picking shells up.

Electric

A battery and motor fire three BBs at a time, automatically if you hold the trigger, from a box or drum magazine. Heavy, costly and a lot of BBs.

Same mechanism, two shapes: a short model with a pistol grip for tight corridors (CYMA CM351 Breacher) and one with a full stock that is easier to aim (CYMA CM350).

Spring pump-action and tri-shot

In a spring shotgun the pump does two jobs at once: it compresses a spring and it moves the next BBs from the shell into the barrels. Pull the trigger and the spring drives a piston forward, which pushes air behind the BBs.

A tri-shot has three thin inner barrels inside the one outer barrel, so every pump sends three BBs out together. Tokyo Marui builds its spring shotguns this way, and the CYMA models in the pictures fire three per pump as well.

Gas shotguns

A gas shotgun keeps the pump but lets gas do the pushing. The pump only loads the BBs, so it moves with a light touch. On the Tokyo Marui M870 the gas sits in a tank inside the stock that you can swap, and a lever sets three or six BBs per shot.

Gas brings its usual bill: you pay for the fuel, the rubber seals want silicone oil, and the power falls on a cold day. British buyers also have to find the gas locally.

Higher is better for the player. This is our own assessment, not a measurement.

Shells, capacity and reloading

Six black shotgun shells with brown bases marked CYMA 3x10 rounds, next to six clear shells with gold-coloured bases marked Specna Arms 30 BBs
Shells are the magazines of a shotgun. Both kinds here hold 30 BBs; the marking 3x10 on the CYMA shells says what that means: ten shots of three.

Loading a shell-fed shotgun

  1. Fill the shell

    Push BBs into the open end until it is full. A speedloader, a tube that pushes BBs in by the handful, saves your thumbs.

  2. Open the loading flap

    Turn the shotgun over. The flap sits underneath, where a real shotgun takes its cartridges.

  3. Push the shell in until it locks

    It only goes in one way round. Close the flap.

  4. Pump and fire

    Ten pumps later the shell is empty: press the release, take it out and put in the next one.

Ten shots go quickly in a building. As a rule of thumb, carry four to six shells for an indoor game, in a pouch or in elastic loops on the stock. Spare shells are sold with the magazines; check that they are made for your model, because not every make takes the same shell.

Everything in Shotguns

Shotguns in CQB and woodland

A spring shotgun indoors and outdoors

Indoors (CQB)

  • Three BBs per pump forgive a hurried aim round a doorway.
  • Always ready: no battery to die, no gas to cool down.
  • Where a site allows only single shots indoors you lose nothing: a pump never fired bursts anyway.
  • A short model turns in the tightest corridor.

In woodland

  • A rifle out-reaches it, so you have to get close.
  • Ten shots per shell, and reloading takes both hands.
  • Light BBs are easily pushed aside by wind and leaves.
A shotgun does not win the long shot. It wins the doorway.

Outdoors a shotgun works best as a second gun on your back for buildings and bunkers, or for a player who enjoys sneaking up close. The low power that makes it welcome indoors also limits its reach.

Site rules and power

Sellers usually ask for a UKARA registration as the evidence that you skirmish: UKARA is the database of regular players that British shops check. A spring shotgun sits far below those power lines. As a rule of thumb each BB leaves with well under one joule, which is why it passes the chronograph, the device that measures BB speed, at practically every site.

Gas and electric models shoot harder and deserve a check against your site's limit. Site rules are separate from the law, so ask before you bring a gas shotgun on its six-BB setting or a model that throws its shells on the floor.

Used spring guns

Upkeep and the usual faults

When a spring shotgun misbehaves

What you see Likely cause What to do
Pump locks or nothing fires The pump was not moved through its full travel Pump fully back and fully forward
Fewer than three BBs come out A dirty barrel or a worn shell Clean all three barrels; try another shell
BBs spill when you load the shell The lip or spring of the shell is worn Replace the shell
Shots drop short Dry or dirty rubbers in the barrels Clean, and use fresh BBs of 0.20 g
Rules of thumb. Store the gun uncocked and without a shell in it.

Buying one of the used spring guns? Ask for a short video of it firing at a sheet of paper: three holes per shot tell you all three barrels work. Look for cracks where the stock meets the body on plastic models, and count the shells that come with it.

Frequently asked questions

How does an airsoft shotgun work?

Most are spring-powered. Pumping the fore-end compresses a spring and loads BBs from a shell into the barrels; the trigger releases the spring, and a piston pushes air behind the BBs. Gas shotguns use gas for the shot, electric ones a battery and motor.

What is a tri-shot shotgun?

A shotgun that fires three BBs with every shot. It has three thin inner barrels inside the outer barrel, each with its own BB. A standard shell holds 30 BBs, so one shell gives ten shots.

Are airsoft shotguns good for CQB?

Yes, CQB airsoft is where they are at their best. Distances are short, three BBs per shot make up for a hurried aim, and a spring shotgun is under every indoor power limit. The price is ten shots per shell and a reload that takes both hands.

Spring or gas shotgun: which should I buy?

Spring first. It is cheap, works in any weather and needs almost no care. Buy gas when you want the lighter, faster pump or six BBs per shot and accept the cost of gas and the upkeep; in the UK you also buy that gas locally.

What shells and BBs do I need?

Shells made for your model, four to six of them for an indoor game, and good 0.20 g BBs. Heavier BBs lose too much speed in a low-powered spring shotgun. Use biodegradable BBs where the site asks for them.

Are shotguns allowed on every site?

A spring pump-action rarely raises a question: its power is low and it fires one shot per pump. Gas models, six-BB settings and shell-ejecting shotguns are where a site may have its own rule. Ask the site before the game day.

Airsoft Guns Buying Guide: How to Choose Your First One

Of all airsoft guns, your first should be the one you can use at your own site on every game day, and for most people that is an electric rifle. This guide walks through the types, the power sources, what each budget level gets you and when second-hand is the better buy. It starts with what a UK buyer can actually order: a realistic gun once you are registered as a regular player (UKARA), a brightly coloured two-tone until then.

AEG Airsoft Guns vs GBB, HPA and Spring: Which Power Source?

An AEG airsoft gun, the electric kind, is the right choice for most players: it works in any weather and costs little to run. Gas blowback (GBB and GBBR) gives you recoil and realistic handling at a higher running cost, HPA gives the most consistent shot if your site allows it, and spring is for sniper rifles and shotguns. This guide explains how each system works and compares cost, upkeep and cold-weather behaviour for British skirmishing.
