Having never used or looked through a red or green dot sight, I have a question:
Is the dot translucent or opaque?

It is a bright point of light reflected off the transparent lens.
For a reasonable visual analogy, look at the point of light generated by a laser pointer. You can technically see what it's illuminating, but for all intents and purposes all you see at that spot is the laser light reflected because of the difference in relative brightness between the laser beam and the background.

BoBo's answer is about right. It's a small, bright dot (more or less circular). It's brighter than what is behind it, so you won't really see "through" it. Generally it obscures much less of the target than a front sight post would. For long guns, most people choose sights with a 1-2 MOA dot. Pretty small.

I can understand that. Yet the most common I see are a 5 MOA.. Thank you, but no thank you.
I did find a couple 1 MOA and a 0.5 MOA, either would be good on my crossbow,I think.
If memory serves, at 50 yards, the dots would be 0.5 inch and 0.25 inch respectively. I have not done the math for dot size at 20 yards.
I don't want "It will hit somewhere in that 2.5 inch circle ..." at 50 yards or less, after it is sighted in that a 5 MOA would give.
5-6 MOA is standard for handguns. 1-2 MOA is far more common for long guns. Don't look at the pistol sights.
And I think you'll find that most front iron sights are a lot fatter than 1-2 MOA.
