4. I have old decrepid eyes. I actually shoot custom printed 8 inch red targets for 100 yard iron sight shooting. I have trouble seeing the target if it is smaller than 8 inches.

I dunno. I actually shoot better with irons than with the red dot sight.

I like the M&P15-22. I don't really know anything about the Center Point Tactical sight, but for $25, it just may not be that reliable. That said, an awful lot can depend on what size the dot is. A 2 MOA dot is going to cover a 2" circle at 100 yards; a 4 MOA dot covers a 4" circle. . . . .meaning the area of the target that will be obscured by the dot at a given distance. Generally speaking, the smaller dot will give you more precise aiming, but it might also be harder for you to see. Also, different dot colors are more visible depending on the background. That's why some sights offer both a red and green dot. Yours also apparently offers different kinds of reticles. You might just try experimenting with different reticle/brightness settings. But if you are using a red reticle against a red target, it might be pretty hard to be accurate.

All of my rifles had magnified optics only until I bought my first AR, so I'm comfortable with optics, and I can't see crap with irons. My M1A came with irons, and I shot it at 200 yards before putting a scope on it, but the target was a 10" steel plate, and the front sight totally obscured it. I got to where I could hit it reliably, but I would not say that it was of much use to me beyond that distance, particularly with any regard to accuracy.

Then, I realized, I shouldn't focus on the dot likt it's an iron front sight. I should focus on the item I am shooting at. After I focused on what I was shooting at, the red dot came into focus.

Anyways, am I crazy or what? I feel more comfortable shooting with irons than with the red dot. The red dot is supposed to be better, right?

1) What is the RDS mounted on?

2) What kind of RDS is it?

3) What kind of iron sights?

4) Generally speaking, I am guessing that as you age and your eyesight begins to deteriorate, you'll come to appreciate an RDS. That said, iron sights are a basic skill that should be mastered.
