I just got a brand new $70 sight put on my bow. Its a vital bow gear tomb stone. Its all metal construction I am having a problem with it. Where I have been adjusting my 30 yard pin up and down, the metal which I tighten the screw onto has been sort of chipping and wearing out. It's not hurting the sight or my shooting right now, but im afraid if it continues to wear out like this my pins will not be able to stay tight. I have only had this sight for a couple of weeks, and it seems like for 70 bucks this shouldnt be happening. Does anyone know what could be happening? Also, has anyone had any luck with Vital Bow Gear's customer service?

Hopefully this all makes sense, its hard to explain whats going on.......

Thanks!
