Big and clear - AIM Sports Inc Dual Illuminated Red Dot Sight

I put this on a VR80 mag-fed 12 ga shotgun, and it works great. Quick and easy to look through and see target. I set it up in first 8 or 10 rounds, and it stayed on target through 150 total 12 ga rounds in one day at range while breaking in the gun. I have tried the green dot and the circle, and like them both. There are a few more choices, but those are what I have used so far. I have a slight astigmatism and was not affected at all. Would definitely recommend if your looking for a scope like this.
