About Our Airsoft Pistons

From increased strength and durability to improved angle of engagement, our huge range of airsoft pistons is the best place to start if you’re looking for an upgrade. Only stocking the best brands in the business, explore pistons from ASG, Modify and more.

The piston in an airsoft electric gun is the driving force behind the air required to launch the BB out of the barrel. It meshes with the teeth on the gears to travel backwards, compressing the spring which in turn launches the piston forward to compress the air in the cylinder and force the BB out of the barrel. 

Your AEG piston is under heavy use every time the gearbox cycles, so it needs to be made from a tough material to last for the tens of thousands of shots you would expect out of an AEG. Though not essential, having a robust material like steel teeth or a steel rack on the piston helps to ensure long-lasting performance.
