Well for three days I had been trying to figure out where in the heck a buzzing noise was coming from on my 2013 Bengal. After making sure all attached accessories were tight, bumping the bow with the palm of my hand and placing my ear next to every component I finally isolated the problem. So if you have a buzzing noise and can't quite figure out where it is tighten these a tad and you problems are solved. No noise now. Bow is very quiet now on release. Same issue on my Silencer got it silenced too.
