What is GBB Airsoft? What is the Difference Between Gas Blowback and Non-Blowback Gas Airsoft Guns
While gas and spring-powered airsoft guns are widely available in the market, AEGs or airsoft electric guns tend to be more common and popular. Their convenience and reliability make them suitable for beginners, hence the widespread use.
However, once you start getting to know the sport better, you might find yourself curious about other available options. The beauty of airsoft is that there are so many exciting choices for equipment so there’s always something different to explore.
For a whole new experience in airsoft, switching to another type of airsoft gun would be a good idea. While you’ll still be playing the same type of games in most likely the same fields and with the same people, the involvement will be different if you’re going to use a different type of weapon.
So if you’re used to using AEGs, a GBB gun might be a nice alternative for you. What exactly is it? Let’s take a closer look below.
What Does GBB Stand for in Airsoft?
GBB stands for ‘gas blowback’. This refers to the type of weapon these guns are. They’re gas-powered and come with a blowback action.
What is a blowback action? Blowback is defined as “a process in which gases expand or travel in a direction opposite to the usual one, especially through escape of pressure or delayed combustion.” In airsoft guns, it refers to the back and forth movement of the slide with each pull of the trigger.
The best way to describe it for those who are unfamiliar with the concept is that it’s similar to an actual firearm’s recoil. It’s just a less severe action since the object being forced out of GBB guns are much lighter than real bullets. As a result, the kick created by GBB airsoft weapons are classified as blowback and not recoil.
How GBB Airsoft Guns Work
GBB airsoft guns work following the principle of potential energy in the form of gas. The pressurized gas is stored in a reservoir inside the airsoft gun, some of which gets released when the trigger is pulled.
Essentially, the trigger opens a slot where the pressurized gas can escape to. This will then push the bb forward while also pushing the slide back. This results in a realistic blowback action that also pulls up another bb in front of the valve then resets the hammer that releases the gas.
It’s a cyclical process that repeats every time you pull the trigger. It ends when the last bb is loaded and the stopper at the side of the gun is engaged. It will stop the slide from moving to its closed position and will keep the shooter from attempting to take shots again.
GBB vs Non-Blowback Gas Airsoft Guns
Not all gas-powered airsoft guns have blowback action. These are known as non-blowback gas airsoft guns. They work pretty much the same way as AEGs and most spring airsoft guns as their slides stay in place while shooting.
Another notable difference between the two is the trigger action. The trigger pull is usually longer and heavier for non-blowback guns due to their double action. This can make them trickier to handle.
Also, non-blowback guns look a lot less realistic compared to GBBs. The latter are typically made to look and feel like actual firearms so they often come with all the details of real weapons. As a result, many find the GBBs to be a lot cooler to shoot with.

Why Consider Getting a GBB Airsoft Gun?
Now that it’s established what a GBB airsoft gun is and what sets it apart from non-blowback types, it’s time to look into its usage. There are actually quite a few reasons why GBB airsoft guns are notable and preferred by many.
If you’re wondering what benefits you’ll get by getting one, here are some good points that you should know about.
One of the biggest reasons why a lot of airsoft players get GBB guns is because they can offer very realistic gameplay. As mentioned above, these guns are nearly identical in many aspects to actual firearms.
The blowback action tends to make these airsoft weapons feel like they’re real firearms. While the impact they create are not identical to the real thing, it proves to be enough for most shooter’s purpose.
If you’ve only played with AEGs before, GBBs will offer you a whole different experience.
Training for real firearms handling
Lots of professionals who use firearms as a part of their jobs also make use of GBB airsoft guns for training for various reasons. For one, they feel like the real deal so they can help maintain one’s muscle memory in handling firearms even if they can’t actually train with actual weapons.
The blowback action in GBB guns are already enough for a lot of shooters to help them get used to the feel of handling actual firearms. The impulse it creates keeps a lot of shooters from getting surprised and intimidated from a real gun’s recoil.
Friendly price tag
It may not seem like it but GBB airsoft weapons are usually around the same price as AEGs. So if you’re worried about the prices of these items, there’s not much to fret about. If you have a budget for an AEG, there’s a good chance that you’ll find a good GBB unit within the same price range.
What might make GBBs a bit costlier than AEGs, however, are the consumables. Aside from bbs, you’ll also need to buy canned gas to make them work.
Proper Handling and Maintenance of GBB Airsoft Guns
If you’re interested in getting a GBB gun, it’s important to learn about its upkeep, too. Caring for GBB airsoft guns is different from handling and maintaining AEGs. To ensure that you’ll keep your GBBs in top shape, here are some important things to keep in mind.
