Got new Cobra DRM sight yesterday and put on my Drenalin today, sighted itin,no problems. Really like it, simple to adjust, BUT one problem, it vibrates. Any suggestions on how I might fix this problem? If can't find solution, goes back .Thanks for any help.

hm, make sure everything is tightened all the way. only suggestion i have

Yes, every thing tight. But still vibrates, and makes noise still. Friend at work said try Limbsaver products on it.Thanks for reply Rory/MO.

I had issues with my sight vibrating and being noisy. I put some limbsavers on mine and it worked great. They are cheap enough that its worth a try. They make the small ones for accesories like sights, but I bought some of the limbsaver insulator strips for your riser and stuck one of those across the top of the sight and it worked like a charm. They are so obsessed with making everything sights so light that they vibrate like crazy. I'll take a solid heavy sight anyday.
