Forgive me for my ignorance. I notice that when your purchasingthe LT BUIS, there are two different choices as far asthe apeture?  What is the difference between these two choices?

One has a standard A2 aperture set, one large, one small and set on different planes so the POI is higher with the little aperture than the big one. the other set has bigger holes, still big and little though, but they are on the same plae and have the same point of impact.

So the one that costs the extra $25 is the one that is set up to have the same point of impact?  Thnx mate

I'm thinking about sending mine back and getting the same plane set, but how do the different plane sights affect POI if you are using a 50 yard/200 meter (RIB) zero?

IIRC when you switch to the LR aperture you're zero'd for 300 or 350M

Usually the little aperture puts you 3-4 minutes high.

OK, thanks guys.  I'll probably just keep it, since I am using small aperture primarily anyway, and after going back and forth between 50 and 25 a few times (because of the size of the space I have to shoot) it is apparent that I'm going to have to fastrack my optics plan. My vision out to 50 just doesn't hold up.
