[QUOTE="green 788, post: 703688, member: 3781"] Wow... Lots to "clarify" here. :) The erector has it OWN lenses... and they take in light from the objective lens, and transmit it to the occular lens. The position of the erector has absolutely nothing to do with optical clarity. And it's a good thing for us long range shooters that it doesn't... because we typically run the optic at a 100 yard zero, and dial up from there. We'll dial from bottom to top... but again, as the erector moves, it's only moving a few thousandths of an inch in each direction, and it's never going to be pointed toward the edge of the objective lens--and its transmission of the exit pupil (beam of light) to the occular lens will generally be centered--never toward the edge of that lens either. The Burris Signature rings are good for getting some additional elevation to enable a rifle's shots to be dialed to longer ranges. I was working with one of our school's test rifles today, and found that it's going to need a boost on the rear of the scope in order to reach 1040 yards... I'll do it with Burris Signatures with the offset inserts. (ordered them about an hour ago from Midway)... But the notion that moving the erector away from its centered position is going to harm clarity of the scope is simply not true... because the erector's lenses move with it, and the only lenses that don't move with the erector are large enough that the miniscule movement of the erector isn't going to point anywhere close to the lens edges--even if you dial it all the way to any extreme. Here is a good link to view scope internals... [url]http://www.shootingvoodoo.com/index.php/articles/anatomy_of_a_tactical_bolt_action_rifle__the_rif/[/url] Dan [/QUOTE]
