Maxx CNC Aluminum Double O-Ring Ball Bearing AEG Piston Head

The Maxx CNC Aluminum Double O-Ring Ball Bearing AEG Piston Head is built for players and techs who want a cleaner, more efficient AEG compression setup. Designed to fit most AEG gearboxes, it combines a lightweight CNC-machined aluminium body with a precise finish that suits both upgrade builds and replacement internals.

In practical use, the ported piston head design helps the O-rings seal more effectively during the firing cycle. That improved compression can help support more consistent FPS from shot to shot, which is exactly what you want when tuning an AEG for dependable skirmish performance.

The double O-ring layout is a key part of what sets this version apart. By improving the air seal at the piston head, it helps make better use of the air volume already being generated by your gearbox. The result is a more efficient compression assembly without adding unnecessary weight to the piston.

Integrated ball bearings are included to help relieve spring tension as the spring rotates under load. That can contribute to smoother cycling and reduced stress in a well-built gearbox, making this Maxx piston head a smart choice when refreshing or refining your internals alongside items such as AEG pistons, cylinder heads or gearbox parts.

For a precise AEG compression upgrade with proven Maxx build quality, add this red piston head to your next gearbox build.
