[:' (][:' (][:' (][:' (]TR sights and I don' t get along. Put a Micro Matrix on my new RazorTec and it lasted exactly 1 shooting sesion before I took that piece of garbage off. Good idea, bad quality. Not worth the $114 I paid for it IMO. If you want to spend big $$$ go with a Spot-Hogg sight, at least they are a quality sight. Alot of people have actually had problems with the sight sitting too low, and when they shoot broadheads they have actually cut the fiber-optics that hang out the bottom of the sight!! I switched to a $44 HOYT Micro-Lite 3 pin sight and it works 10X' s better than that POC TR sight. I was warned by alot of people about the down side of and poor quality of TR sights, man I wish I had listened to them. Be warned some people like these sights, but more people hate em!
