Exactly what i wanted - Meprolight AR15/M16 4 Dot Peep Rear Night Sights

I was unsure what to expect based on some of the reviews, but this rear peep sight is awesome, it glows just the right amount. The dots give you a blur as a peep sight would, letting you focus on the front post looking through the four blurry rear dots. I paired it with a different brand tritium front sight. Really glad I found a good iron sight nighttime solution. I think the people that have this a bad review are not familiar with how bright tritium is. If this were any brighter it would not be good because it's the rear sight you only want a dim glow right in your eye.
