About Our Airsoft Piston Heads

Take your AEG to the next level with a fresh airsoft piston head. Lightweight and built for longevity, our high-quality piston heads only ever come from the best named brands on the market, such as ASG and Modify. 

###pairsoft piston and is the part that actually compresses the air inside the cylinder. It requires a good seal between the cylinder and edge of the piston head, but still needs to be able to move freely. 

Some piston heads allow air in the front of them to 'inflate' the o-ring as it travels forward. This helps improve compression and air seal, without constantly pressing on the side of the cylinder. Some are mounted on bearings to assist with free movement and prevent snagging inside the cylinder.

If you’d like more information before you decide which piston head is right for you, feel free to get in touch with one of our technical experts!
