This is a new variation on the gun stock idea for the Oculus Touch. This is designed as a low profile add-on to the controllers so you can easily go from having two independent hands to a locked gun stock. All you have to do is put the two halves together and they will lock. They are retained together with magnets and steel strips. Putting them together and pulling them apart can easily be done in game whenever you want. You will not need to stop the game to swap them in or out. Since these are low profile and don't get in the way of most regular VR motions, I leave mine on my Touch controllers all the time.
