For a quite a while I was wondering where I did see those type of clamps before. Grabbing my old angle grinder I noticed I had those all along. Those are VERY close to what I see on the real blaster. Those clamps are welded on to the protector, but can be removed. They come in different sizes, and the newer type clamps have different systems to secore the protector, but the older type clamps match those from the movie gun. I used my flash tube to see how they fit, and they are right on when it comes to diameter. What do you think?
