In my opinion, it's a great thing, unfortunately I can't list all of its advantages and disadvantages. The NB mount is installed on the WE Hi-Capa Dragon 7 pistol visible in the photos (the pistol also has a 5KU charging handle installed). I consider the mount to be very good, I had no problem installing it on my replica, the RIS rail is of good quality, you can adjust and move it, and you can change it to another rail. My mount is slightly tilted, I'm not sure if that's how it's supposed to be, but as for the sight added to it, everything definitely works together at a distance of 5-10 meters.
