Duralumin V2 / M4 AEG Gearbox Brace

AirsoftParts Duralumin V2 Gearbox Brace for M4 AEGs
Its purpose is to provide additional support for the gearbox and help distribute mechanical stress generated during firing, reducing the risk of the gearbox shell cracking. The brace uses adjustable sliding pins whose position can be adapted during installation to the space between the gearbox and receiver and then secured with locking screws. The design allows wiring to be routed towards the handguard, which is important for guns with front-wired configurations. The duralumin construction offers high durability at a reasonable weight, while the plastic nut further helps reduce the overall weight of the component. Due to differences in design and manufacturing tolerances between individual M4 models, unconditional compatibility with every model should not be assumed without possible fitting.
Key Features

Additional Gearbox Support
The brace is positioned between the gearbox and the receiver, where it helps distribute mechanical stress and reduce the risk of the gearbox shell cracking during firing.

Adjustable Sliding Pins
A pair of sliding pins allows the brace to be adjusted to the specific gun configuration. Once adjusted, their position can be securely fixed using locking screws.

Durable Duralumin Construction
The duralumin construction combines strength with low weight, allowing the brace to provide mechanical support without unnecessarily increasing the weight of the build.

Space for Wiring
The brace design allows wiring to be easily routed into the handguard, making it suitable for configurations with the battery and wiring located in the front of the gun.
