[QUOTE="Broz, post: 1149426, member: 7503"] True and the reason I stated 100 yard zero. With the 100 yard zero the line of sight differences are more like 1.5 moa. This small difference will usually be less than the machining tolerances stacked up. Mostly in runs of actions and receiver top differences. Then you have the small issues like bore center and barrel centerline as well. That's why I stated "in a perfect world and also why I suggested the 20 would allow more room for error than shooting for the 30 when he only had 32.5 "in a perfect world" to borrow it from. I myself have seen tolerances vary in less expensive rails. Like a 20 moa EGW I once purchased new that had 50 moa. Good thing I had a Nighrforce with 100 moa total elevation. Thus the reason in posts I stated " the use of quality rail" Thanks Jeff [/QUOTE]
