In short
- Ask for the chrono reading first. A chrono measures the speed of the BB, the 6 mm plastic ball. With the BB weight it gives the energy in joules: the number the law and your site both look at.
- Every type wears in its own place. Electric rifles in gears and wiring, gas guns in seals and magazines, spring snipers in the parts that hold the spring, compressed-air (HPA) builds in the pressure regulator and the tank.
- A realistic gun needs evidence from you. A UK seller of a realistic gun, a RIF in the law, has to ask for it: usually a UKARA registration, which shows you play at a registered site. A two-tone, mostly a bright colour, needs none.
- Pay with buyer protection, test, then release. The money is held until you confirm receipt.
Before you message the seller
Most disappointments with used airsoft guns start before the first message. Know three things: the power limit of your site, the type that suits it (electric, gas, spring or HPA, which runs on compressed air from a tank) and whether you may buy a realistic gun or need a two-tone.
Then look at where the gun is. Most listings on Airsoft Bazaar come from the Netherlands and Belgium, so start with the listings in the UK: a gun you can collect is a gun you can test. One sent from the EU means import charges.

See it work before you pay
Ask for a video and a chrono reading. Pay with buyer protection, so the money is held until you have checked the parcel.
How buyer protection worksKeep questions and payment in the Airsoft Bazaar chat. Without them we cannot look into a problem.
Reading the listing and the photos
A good listing answers most questions before you ask: brand and model, what is included, what was changed inside and what is wrong with it. A gun that has clearly been played with and is described honestly beats a spotless one with a single line of text.
Photos show care, not the inside. Never read a photo as a diagnosis: use it to decide what to ask next. Look at the seller's other listings and reviews too.
The photos and video to ask for
-
Both sides, in daylight. With a close-up of every flaw the listing mentions.
-
The places that wear. The battery compartment on an electric gun, both ends of each magazine on a gas gun.
-
A note with name and date. Handwritten and in the picture: the seller has the gun today.
-
A video of it firing. Single shots, then a short burst.
Used airsoft guns: the checklist per type
Pick your type: the inspection from the outside in
Electric rifle (AEG)
- Body and barrel: no cracks, nothing wobbles.
- Battery compartment: wires whole, plug not melted or taped.
- Single shots: twenty trigger pulls, twenty shots.
- Automatic fire: an even sound, no grinding.
- Hop-up, the part that gives the BB backspin so it flies further: it adjusts and holds.
- Chrono on 0.20 g, and a list of changed parts.
Gas pistol or gas rifle
- Slide, the moving top half: no cracks, above all at the front.
- It moves smoothly by hand.
- Every magazine filled with gas: no hiss, still full after an hour.
- Loading nozzle, the part that pushes each BB into the barrel: no cracks.
- The slide stays back after the last shot.
- Chrono at room temperature, and count the magazines.
Spring or bolt-action sniper
- Stock and body: no cracks around the screws.
- Bolt, the handle you pull back for each shot: smooth, and it locks every time.
- Closing the bolt does not fire the gun. If it does, it is unsafe until repaired.
- Barrel straight and clean; the hop-up, which gives the BB backspin, adjusts and holds.
- Chrono with the BB weight, and the list of upgraded parts.
HPA build
- Tank: the test date on the label, no dents or deep scratches.
- Regulator, which lowers the tank pressure to working pressure: the gauge holds steady.
- Line (the hose): no cuts, no hissing with the air on.
- Engine, the unit in the gun that fires the BB: make, model and last service.
- Chrono with the pressure noted, on 0.20 g and your own BB weight.

AEG checklist: how to test a second-hand electric rifle
An AEG (automatic electric gun) uses a battery and a motor to turn a set of gears, the gearbox, which fires the BB. Among used AEGs most of the wear sits where you cannot see it, so you test with your ears and a chrono.
Testing a used AEG in five minutes
-
Look at the plug
The small white Tamiya plug and the flat red T-plug (Deans) are the common ones. Look for melted plastic or taped wires.
-
Fire twenty single shots
One pull, one shot. A double shot or a dead pull points at the trigger contacts or the electronics.
-
Listen to a short burst
You want an even hum. A screech or a rattle can mean badly set gears.
-
Chrono ten shots on 0.20 g
Readings close together are healthy. A wide spread suggests air is escaping inside.

GBB pistol and GBBR checklist
A gas blowback pistol (GBB) or rifle (GBBR) keeps its gas in the magazine and uses a little for every shot, to fire the BB and to throw the slide, the top half of a pistol, back. The parts that fail are mostly rubber seals, so with a used gas gun you test every magazine, not only the gun.
Gas loses pressure in the cold, so ask for a chrono reading taken indoors: the warm reading must stay under your site limit.
Sniper and spring gun checklist
A spring gun has the fewest parts: you pull the bolt back, which compresses a spring, and the trigger lets it go. A used spring rifle in standard form rarely hides much. The risk sits in upgraded ones: a stronger spring wears the parts that hold it back, unless those were upgraded too. A rifle that fires when you close the bolt has reached that point.
HPA build checklist
HPA stands for high-pressure air: a tank feeds air through a hose to a unit in the gun that fires the BB. A used HPA gun is four purchases in one, gun, engine, regulator and tank, and each can be worn by itself.
The power follows the pressure set on the regulator, so a chrono reading only counts with the pressure it was taken at. Many sites have their own HPA rules: ask yours first.
Questions to ask every seller
Four questions, asked in the chat so the answers are on record
| Ask this | Why |
|---|---|
| Where did you buy it, and has it been opened? | A receipt and a parts list add trust; an unnamed "upgrade" adds questions |
| What is wrong with it, and what is included? | Every used gun has something. Deal with the seller who names it |
| What does it chrono at, with which BB weight? | Legal or not, allowed at your site or not |
| Is it a RIF or a two-tone, and what evidence do you need? | A UK seller of a realistic gun has to ask |
The chrono reading: the number UK buyers ask for first
Speed alone says little: the same speed with a heavier BB is more energy. So ask for the speed in feet per second (FPS) together with the BB weight, ideally on 0.20 g, the weight most site limits are quoted for.
For gas and HPA guns, ask for a second reading with heavy BBs. In some guns a heavier BB leaves with more energy, and the highest figure is the one that counts.
- 1.3 joules: Great Britain, automatic fire
- about 374 FPS
- 2.5 joules: Great Britain, every other gun
- about 519 FPS
- 1 joule: Northern Ireland
- about 328 FPS

Red flags and when to walk away
Red flags in a listing or a chat
| What you read or see | What it often means | What to do |
|---|---|---|
| Photos that look like shop photos | The seller may not have the gun | Ask for a photo with a note: name and date |
| "Upgraded" without a parts list | Unknown work | Ask which parts and who fitted them |
| Range or power as the selling point | Sales talk, or a gun above your site limit | Ask for the chrono reading |
| A price far below similar listings, or "cannot test it" | A hidden fault, or no gun at all | No test, no deal |
| Bank transfer or "friends and family" only | You pay without protection | Ask for buyer protection, or walk away |
Not every fault is a reason to walk away. A tired hop-up rubber, a weak spring or a dried seal are wear parts, and a seller who names them is being straight with you. Walk away when you cannot test, cannot pay safely or cannot get a straight answer.

What should I check on a used airsoft gun?
The outside, the function and the energy, in that order. Look for cracks, wobble and damaged wiring or seals. Then fire it and get a chrono reading with the BB weight.
How do I test a second-hand AEG?
With a charged battery, your ears and a chrono. Fire twenty single shots and a short burst, then chrono ten shots. You want an even sound and readings close together.
How do I check a gas pistol for leaks?
Fill every magazine with gas at room temperature and listen for a hiss. Then wait an hour and fire them. A magazine that is weak or empty by then has a slow leak.
Which photos should I ask the seller for?
Both sides in daylight, every flaw the listing mentions and the places that wear. Add a handwritten note with the seller's name and the date, and a video of the gun firing.
What are red flags in a listing?
Shop photos, "upgraded" without a parts list, range or power as the selling point and a price far below similar listings. In the chat: no test, and bank transfer only. One flag is a reason to ask more; two or three, to walk away.
Should I ask for a chrono reading?
Yes, always, and with the BB weight. In Great Britain a gun that can exceed 1.3 joules with automatic fire, or 2.5 joules otherwise, is a firearm in law, and your site sets its own limit.
