Product Overview
The CORE V2 Gearbox shell from Specna Arms is designed for M4/AR-15 AEG replicas but is also the correct shell to use for an AEG SMG-5/MP-5 gearbox build. This shell includes 8mm bushings, and features radiused corners on the cylinder window, preventing a common failure in AEG gearboxes using high powered springs. The rear of the gearbox is open for the use of a quick-change spring guide, allowing you to change your spring without having to open the gearbox.
