CNC machined bracing block for V2 AEG gearboxes. 
This block has spring loaded tabs which can be locked securely in place to transfer impact loads from the front of the gerbox shell to the receiver.

This is a cheap and effective way to reduce gearbox cracking in systems where replacement gearboxes are not available or overly expensive.
