Understanding the parts of your GBB airsoft gun


Before we dive into the upgrade process, it's essential to understand the different parts of your GBB airsoft gun. A GBB airsoft gun consists of several components, including the barrel, hop-up unit, gas system, and magazine.


The barrel is part of the gun that the BB travels through. The hop-up unit is responsible for applying backspin to the BB, which helps to increase its range and accuracy. The gas system is what powers the gun and propels the BB out of the barrel. The magazine is where the BBs are stored and fed into the gun.

The new barrel should be made of high-quality material like stainless steel and have a tighter bore diameter around 6.03mm. A tight bore diameter will help to improve your gun's accuracy by reducing the amount of wobble the BB experiences as it travels down the barrel. But sometime it will be too tighter and caused BB stock in the barrel. In our opinion 6.03mm is the best diameter.


Once you've installed the new barrel, you'll need to make sure it's properly aligned and secured in place. You can test the accuracy of your new barrel by shooting a few rounds and adjusting the hop-up unit as needed.


2. Upgrading the hop-up unit

The hop-up unit is responsible for applying backspin to the BB, which helps to increase its range and accuracy. Upgrading your hop-up unit can significantly improve your gun's performance. The Hop-up unit contains the hop-up rubber, hop-up nob, and hop-up chamber.

And high quality hop-up chamber should able provide good air sealing to increase FPS and bring you further shooting distance. Finally adjustable settings will allow you to fine-tune your hop-up to achieve the best possible performance.


Once you've installed the new hop-up unit, you'll need to test it by shooting a few rounds and adjusting the settings as needed. Properly adjusting the hop-up unit is critical to achieving maximum range and accuracy.




3. Upgrading the gas system

The gas system is what powers your GBB airsoft gun and propels the BB out of the barrel. Upgrading your gas system can significantly improve your gun's power and consistency. The gas system include, nozzle, valve, fire control set etc


To upgrade your gas system, you'll need to replace the orignal components with new ones. The new components should be made of high-quality materials and designed to improve your gun's performance. A better nozzle come with better gas consuming effiency which allow you to use GBB in colder weather and more stable performance, some with NPAS even able to adjust FPS. Good valve also improve effiency on gas consuming.


Once you've installed the new gas system components, you'll need to test your gun to make sure it's functioning correctly. You should also test your gun's consistency by firing several rounds and measuring their velocity.
