||this is agreat sight looks really on good on an M4 or an M16. I have it on my echo 1 M4 and it looks fantastic. the only reason i gave it four stars is because it gives off a little glare on the first brightness setting if you are playing inside and the iron sights aren't really acurate. don't really have to use the brightest setting because the first is bright enough for outside any way.
First setting is bright enough for outside
Iron sights gives it that extra look
Iron sights are kinda off key
Gives off a little bit of glare if you are playing inside or at night.
