Prometheus Cylinder Type E

This Type E cylinder is optimized for inner barrels between 201mm and 250mm. Using it with a barrel outside this range may lead to inconsistent air volume and poor performance.

While it is designed specifically for Tokyo Marui AEGs, it is generally compatible with most standard Tokyo Marui-spec gearboxes. However, you should verify your specific gearbox shell dimensions before installation, as some proprietary brands may require slight modifications.

The ribbed design isn't just aesthetic; it adds structural rigidity to the cylinder walls. This helps prevent deformation under high-stress firing cycles, ensuring a more consistent air seal over time.

Yes, the high-polish finish reduces friction between the piston head and the cylinder wall. This smoother movement helps maintain a better air seal and can slightly improve the efficiency of your gearbox cycle.

Yes, even with a polished surface, you should apply a thin, even coat of high-quality silicone-based grease to the interior. This ensures the piston head moves freely and maintains a proper seal.
