AEG vs GBB vs Spring: Which Airsoft Gun Type?

Ook in het Nederlands: NL
About to buy your first airsoft gun? You'll quickly run into three abbreviations: AEG, GBB and spring. These aren't brands or models, but three ways a replica fires a BB. The power system you pick shapes most of your experience: whether you shoot semi or full auto, how much maintenance you face, what it costs and how reliable your gun is on a cold game day. Below we explain all three and tell you honestly what a beginner is best off doing.
AEG: the electric all-rounder
An AEG (Automatic Electric Gun) is powered by a battery. It drives an electric motor that, through a gearbox, compresses and releases a spring-piston system. The result: you can shoot semi-automatic and usually full-auto too, with large magazines (mid-caps or hi-caps) holding plenty of BBs.
Pros:
- Versatile: semi and full auto, usable indoors and outdoors.
- Reliable in all weather, including the cold (a battery is far less affected than gas).
- Good value at entry level, with a huge supply of upgrades and spare parts.
- Cheap to run: you only need BBs and a charged battery.
Cons:
- You depend on your battery; forget to charge it and you're out. A spare battery and a charger are recommended.
- The gearbox needs maintenance over time (lubrication, occasional part replacement).
- Less "realistic" shooting feel than gas, because there's no recoil.
GBB: gas blowback for the real feel
A GBB (Gas Blow Back) runs on gas, usually green gas or CO2. With every shot, gas not only fires the BB but also kicks the slide or bolt backwards: the blowback. That gives tangible recoil and a realistic sound. You'll find GBB mostly in pistols, but also in GBBRs (rifles).
Pros:
- The most realistic shooting feel thanks to the recoil and moving parts.
- Pistols are ideal as a sidearm or for players who love realism.
Cons:
- Cold weather is the big weakness. Green gas loses pressure at low temperatures, so your gun shoots slower or jams. In winter, CO2 or an AEG often performs better.
- Higher maintenance: rubber seals can wear or leak and need looking after.
- More expensive to run: you keep paying for gas capsules or green gas.
- Magazines are smaller and pricier, so you reload more often.
Spring: manual, simple and cheap
A spring replica is cocked by hand before every shot, often by pulling a slide or pump. No battery, no gas: the energy comes purely from a spring you cock yourself. Spring is common in cheap starter pistols and in sniper rifles, where one shot at a time is actually what you want.
Pros:
- Cheapest to buy and almost free to run (BBs only).
- Very reliable and weatherproof: no battery or gas to let you down.
- Barely any maintenance.
Cons:
- Single-shot only: re-cock after every shot, so no rapid fire.
- Cheap spring pistols are often low quality and not ideal as a primary skirmish weapon.
- A serious spring sniper rifle, on the other hand, takes practice and is a specialist choice, not an easy start.
What should a beginner pick?
For most beginners, a reliable entry-level AEG is the best choice. You get semi and full auto, it works year-round (including the cold), maintenance is manageable, and there's a large supply of parts and help. A GBB pistol is a nice addition as a sidearm once you know the sport suits you, and you'll usually skip spring as a primary skirmish weapon, unless you deliberately go for the sniper game.
