Excellent sight - best buy - ATN Ultra Sight Red Dot Reflex Sight DTRXULSTM

I've used several red dot/reflex sights and I am sick and tired of reading reviews by children who play airsoft. Please, if you play airsoft, feel free not to comment on how this or that works on your toy. This web sight is for shooters who use firearms. Getting that out of the way, the distance between the laser and the crystal matters because the additional millimeters mean the "dot" will move less and naturally encourage you to shoot from the same spot every time. This means the sight will help beginner shooters to sight-in more consistently, placing their cheek bone and nose in the same position for every shot - thus making the shooter more accurate overall. I highly encourage anyone looking for a reliable reflex sight (that isn't more than $200) to spend the extra money to purchase this model or one from ATN. Take it or leave it - I've used this sight for more than four years and haven't had to replace the batteries yet. I can stand and shoot at targets distant to 50 meters with a four inch Circular error probability (meaning the shots will end up hitting within a 4 inch diameter) using the two-eye shooting technique in rapid succession (6 shots/30 seconds from a standing position).
Pros: sight picture, accuracy, brightness, battery life, fitting.
Cons: screws used to tighten sight onto rail need to be thumb screws
