• Aluminum version 2 Gearbox shell construction
• Reinforced critical areas such as the front of the gearbox shell and the spring guide base, while paying close attention to the cylinder window geometry to minimize stress on the pneumatic system's axis
• To ensure seamless interaction between the piston and piston gear, Specna has included inspection holes for checking the Angle of Engagement (AOE) and pre-cocking
• With future HPA upgrades in mind, Specna has designed the gearbox shell to allow for horizontal adjustment, ensuring optimal performance and a great air seal
• 8mm J-cage ball bearings on both the sector and bevel gears
• Inspection hole for releasing the anti-reversal latch and checking the bevel gear condition
• A small screw located behind the trigger axis allows for pre-tension adjustment on any V2 gearbox trigger
• Shell designed to work with magazine sensors for GATE® ASTER II and TITAN II systems

The second most commonly modified component of an airsoft replica is the gearbox. In this case, we decided not to compromise and completely redesigned the heart of the PRIME line. We started from scratch, designing an entirely new gearbox shell that offers not only exceptional durability but also numerous features for those who want to know how their replica works.

The AETHER gearbox shell has been engineered to provide the highest durability available in a factory replica. At the same time, it adheres to one of our core brand principles: high compatibility with parts from other manufacturers. This makes it an excellent foundation for the most demanding custom builds and can be used in other replicas as well.
