So figured why i can not hit the broad side of a barn with my red dot. I need a riser.

Most things i read about them for absolute is in reference to a 25mm style (trs 25 ect). my red dot is a 40mm so I am thinking that would make the normal riser (.83) closer to a lower 1/3 due to the increased size of the tube. is there another size, something shorter than the .83 as there is a 7.5mm or about .3 ish difference on the tube radius.

Does anybody in the hive mind have any insite or knowledge on this that could make a suggestion to help?
