OP - your problem is somewhat trivial. I've taken the light apart and know what you're talking about. If the screws get loose, use some light strength Loctite or any other bolt fastener. Just make sure you go with the "light" stuff so that you can remove it. There are multiple screws in the light and ultimately the QRM is screwed into the aluminum body. It is quite sturdy.
DR customer service has always been top notch for me. I don't know where you got the light, but you should be able to take it to a dealer and have them handle the process. If you don't want to deal with DR, you'll have to get 2 pieces (well, sounds like it): a small spring and a ball bearing. You can buy ball bearings online from places like McMaster:

Look for assorted small springs on eBay.
Finding the right parts should not take more than 30 minutes and the fix takes 10 minutes tops.
