I really like the rail but since I am using the monster atn 4k pro my mounts are already extra high at 1.54" and the scope is resting on the rail and I don't want to go any higher. It also uses a special adapter so you can use any ar raill that will screw on I just like the wide inside so it protects the barrel and moderator. $100 shipped. Any information feel free to ask.
