Saw this scope on EBAY for £29.99 , its a copy of the leupold MK4 scope, side parallax, easy adjust turrets, mildot reticule illuminate (red or green) 3.5 -10 mag , 40mm with a 30mm tube. Quality is very good optics are clear and the parallax adjustment is good. I have put this on the TX200hc and so far very easy to zero and has held its zero since. Overall for £30 quid this is good value.
