MAXX AEG Piston Head

Yes, this piston head is designed for universal compatibility with standard AEG gearboxes. However, because internal tolerances can vary between brands, we always recommend checking your specific piston's thread pitch to ensure a secure fit.

The dual O-ring configuration provides a more consistent air seal compared to single-ring designs. This helps minimize air leakage during the compression cycle, which leads to more stable muzzle velocity and better overall pneumatic efficiency.

The integrated ball bearing allows the spring to rotate freely as it compresses and decompresses. This reduces spring torsion and friction, which prevents spring binding and helps extend the lifespan of both your spring and piston assembly.

While aluminum is heavier than standard polymer, this piston head is CNC-machined to be as lightweight as possible without sacrificing durability. The slight increase in mass is generally negligible for most builds and is often offset by the improved compression consistency.

Yes, applying a light coat of silicone-based grease to the O-rings is essential. This ensures a smooth seal against the cylinder wall and prevents the O-rings from drying out or wearing down prematurely.
