Well built - Trijicon 1x38 Sealed Reflex Sight (SRS)

Very nice optic extremely rugged and robust red dot. It is crisp and everything on it is nice. The only problems I am having is the fact that it will turn on by itself on which is aggravating because if it’s turned on it will drain the battery but at the same time the battery will last three years on the lower settings but still just knowing that kind of aggravates me also you can’t just use any AA battery it has to be a energizer ultimate lithium battery or it will shut off when your shooting due to the fact that all other AA batteries are just slightly smaller the the Energizer battery.
