[ARCHIVED THREAD] - level rail system Q??

Posted: 7/15/2007 2:12:25 PM EDT

I have a CMMG 10.5 upper with DD 9.5 lite ext rail. The rail is not quite level with my upper and I want to make it level. I want to mount my scope up front or on the receiver depending on the situation.
ANy methods on how to line it up right?
