AirsoftPro aluminum silent piston head with bearing in blue finish is an upgrade part designed for AEG airsoft guns that helps improve air seal efficiency while reducing impact noise during gearbox operation. Thanks to the combination of an aluminum body, rubber damping pad, and integrated bearing, it contributes to smoother operation and improved air compression.

For more than 25 years, we know what you like about airsoft.
This piston head uses a system of air channels that expand the O-ring during compression, improving the seal between the piston head and cylinder. Compared to standard plastic piston heads, it can utilize compressed air more efficiently and contribute to more consistent gun performance. The rubber damping pad also helps absorb piston impacts, which may reduce gearbox noise. The integrated bearing allows the spring to rotate naturally around its axis during compression, reducing spring stress and resistance throughout the cycle. For proper function, it must be used with a cylinder head featuring a funnel-shaped inlet.
Six air channels distribute pressure beneath the O-ring, allowing it to expand during firing and create a tighter seal between the piston head and cylinder.
The front of the piston head is equipped with a rubber pad that helps absorb piston impacts and reduce gearbox noise.
The bearing allows the spring to rotate more freely during compression, reducing resistance and spring stress.
The piston head body is made of aluminum, offering greater durability than standard plastic alternatives.
Best results are achieved when used with a cylinder head featuring a funnel-shaped inlet, with which it forms a fully compatible assembly.
