So I have this brand new Sendero I am working on.... I mounted a Nightforce one piece base on it, and was getting ready to mount my scope. But as you can see in the pics, when I put a level on the base, the rear of the base reads much differently than the front. I originally put a Weaver base on it and thought that the cause of this was the Weaver base. So I sprung for a Nightforce but have the same results... I have a quality machinist level by the way, but for the pics the cheap plastic level shows better... The holes all lined up nicely... I don't want to continue on and attempt to make this a shooter if this is a problem... any educated opinions out there??
