I have the silver hair and gold in my teeth also but the lead is all over and getting worse each day!!
The burris eliminator 3 comes with the scope built-in rail that sits into a weaver rail, I don't think you can use a level on it, once it is mounted you can't adjust it left or right. They do send shims in case you have a elevated rail on your gun so you can get a 100 yard zero. The scope's ballistics are set up at 100 yard zero with a drop number at 750 yards.
