Hello, all. I have a bit of confusion over the magnification of the optical sight on the QBU-88. From photos on this sight, it would appear to be the same sight as on the JS 7.62mm (has this been type-classified or officially adopted yet?), which is described as being a variable 3x or 9x sight. However, in the description for the QBU-88 it is described as being a 4x sight.
