Yeah I got one and yes the ARD is kinda hard to screw on. On mine I believe its because it is a very fine thread and has to be perfectly square before you start to screw it on. I like the scope, my wife loves it. She says its the easiest scope she has ever used to get on target. Its not the best thing since sliced bread, nor all that new of an ideal. All in all I like it for hunting and when you get used to it punching paper ain't that hard. Good scope and I'm glad I bought it.
