Collection: Airsoft GBB Rifles

GBB (Gas Blow Back) is the most realistic platform currently in the airsoft market. For the airsoft gun to shoot properly, the user must manipulate it like a real firearm. Due to their realistic nature, some law enforcement and military agencies use them as training tools.

A gas blowback airsoft gun utilities a gas reservoir storing pressurized gas (similar to propane gas) known as top gas/ green gas/Co2. Whenever the user pulls the trigger, a knocker will hit the valve on the gas reservoir, causing it to release a small amount of pressurized gas into the GBB platform. The gas will first push the BB out of the chamber, causing it to fire; the remaining amount of gas will cause the rifle's bolt to move back so the airsoft gun can load the second round for a follow-up shot. However, gas-powered airsoft guns are quite prone to cold weather; when shot too fast, a cool-down effect might occur resulting in a significant fps drop.
