How does MOA work with a red dot scope?

I was looking at a red dot 'scope' today that had four settings, 4, 8, 12 and 16 MOA. I understand the concept of MOA in terms of defining the accuracy of a firearm, but not sure if I understand how it is applied to a red dot.

Does 4 MOA mean the red dot will cover approximately 4" of the target at 100 yards?

Thanks,


Randy

Yes you are correct.

That's why I love the Eotechs... 1 MOA dot, 65 MOA ring. A 4MOA dot is covering 12" at 300 yards.

Just because, why not? Technically:

One MOA is approximately 1.0471975511966 inches at 100 yards, so:

4 MOA at 100 yards would be 4.18879020476 inches (give or take) so actually closer to 4.2 inches than 4.0

Because of where & how we hunt Red Dots are about all we use. Have 2 of the new Micros, one on a .35 Rem and one on a O/U 45-70, also have 2 Bushnell Trophys, one on a .243 Win Single shot and one on a rifled 20 ga barrel for the same action. And there are 2 old Tasco Pro Points, one on a TC Contender .44 mag and one that is on a SXS Rifled 20ga.

We hunt thick woods & swamps, both sitting in portable stands and stalking. Almost everything we shoot is closer than 50 yards, the great proportion under 25 yards.

One really nice thing about a Red Dot, beyond the fact that you shoot it with both eyes open just as you would a peep sight which makes for quick target aquisition, is the UNLIMITED EYE RELIEF. You can literally twist around in almost any direction with the gun any distance from you and so long as the dot is on the target you're good to go.

That is a very useful thing at times..........

Technical nit-pickers as bad as the grammer police.
