Weapon Attachment system and mechanism | Galactic Reign | Microsoft

This is a Concept that I've created for the game "Galactic Reign" for Microsoft. I had to design a mechanical system that attaches the weapons to the space ships. This mechanical system is unified and has to work on all the weapon systems. It would allow the weapon to swivel and rotate and would give it an appropriate range of motion to fire in all directions. The pencil sketch is that system.
