I am fairly new to the shooting sports and am considering putting a scope or possibly an Aimpoint on my Ruger MK2 (KMK678GC). I picked up one of Clark Customs excellent Weaver scope bases to replace the Ruger propriatory one, and on researching optic devices the term MOA is referenced but I have yet to find an explanation on what it means. It seems critical, as the various scopes use this for quality comparisons.

Need Explanation of MOA for Optics

MOA is Minute of Angle. It is roughly 1" at 100 yds, 2" at 200 yds, etc. So a gun with MOA of 1 would shoot groups of 1" at 100 yds. A 1/2 MOA is groups of 1/2" at 100 yds.
In regards to scopes, it is how much clicks on the scope move the point of impact. A scope with 1/4" MOA will move it's point of impact 1/4" at 100 yds. 4 clicks would move it 1".

Different Purposes

Well, they are used for different purposes. If you want to shoot a half-inch hole in paper at 100 yards, then you definitely need a good scope. If you want to be able to hit a target in the center of a rubber tire rolling down a hill, the Aimpoint is probably a better choice. One's more precise, the other is faster to pick up moving targets. Both have their place, depending upon your needs.This info definately is leading me away from Red-Dot scopes with a MOA of 4 !!

You may be confusing the size of the dot with the resolution on the adjustment dials.
MOA is just a term used to represent an angle that subtends 1/60th of a degree.
My Aimpoint Comp ML features a 3 MOA dot. That means the dot appears to be 3" in diameter at 100 yards.
My Comp ML also features 1/2 MOA windage and elevation dials. They are set to change the point of impact 1/2" per 100 yards distance per 'click'.
