Help: Gun Test Required

Hi, 

For my VR Rail Shooter there seems to be an intermittent fault, the triggers occasionally fire the wrong guns. It mainly seems to happen on other peoples computers!?!?

I have created a little test scene, nothing fancy, to check if the problem is now solved. 

If you have 2 minutes to check and report back, that would be greatly appreciated. 

Thanks

Update: Thanks for the people who have helped test the game, this problem is now fixed.
