Gearbox V2 Skeleton Aether CNC Specna Arms shell

The Skeleton Æther V2 gearbox shell from Specna Arms is a high-performance internal part from the Prime range, designed for AEG M4 and M16 replicas using a version 2 gearbox. Machined from CNC-milled 7075 aluminum, it is compatible with power springs up to M140 and accepts standard V2 upgrade parts. It's aimed at demanding technicians and players looking for a solid, upgradeable base for high-performance assembly or original shell replacement.

Its Skeleton design incorporates several inspection windows for checking engagement angle alignment, pre-cocking position and motor pinion without complete hull disassembly. A window for disengaging the non-return clutch facilitates interventions under tension, while a trigger travel adjustment screw is included to fine-tune shooting responsiveness. The hull is supplied with a set of 8mm J-Cage bearings and nine mounting screws. For technicians wishing to reduce intervention times without sacrificing mechanical robustness, the Æther V2 represents a particularly accomplished basis for work.
