This part will be valuable to anyone who has plans to upgrade their airsoft AUG AEG. It replaces the plate that separates the gearbox and the battery. This plate does two things for an upgraded AUG:
- Open up space that the stock plate covers to fit larger battery or MOSFET
- Improve air seal by locking gearbox to prevent bounce with heavy recoil or ROF
The back of the plate can accomodate a rubber washer or o-ring to press the gearbox forward. This helps with air seal and consistent loading. The extension arm braces against the top of the body to reduce flex.
