Sorry, man, I haven't quite figured out the minute of angle thing yet...

MOA equates out to 1.047" @ 100 yds. You get the point by now, right?
If you want the whole dirty details:

An angle of 1 degree is subdivided into 60 minutes of angle.

The linear distance between the legs of an angle measuring 1 minute of angle is 1.047 inches at 100yards from the point of origin of the angle. That linear distance is rounded down to 1 inch for practical purposes.

According to the law of similar triangles, the distance between the legs of an angle measuring 1 minute of angle is 2" at 200 yards from the angle's origin, 3" at 300 yards, and so on and so forth. Therefore, 1 MOA is .5" at 50 yards.

Dude, you're bringing back bad memories of advanced geometry in college.

It's about 4" low when apeture is flush with the site base. I raised it up 3.75". Is that normal? Using a Troy rear BUIS large apeture.

Huh? That's simple trigonometry I learned in high school.

You wanted to know what a minute of angle is and how it is used to describe ballistics trajectory.....

Well, there you go.
