I've got one which is my second one because the first one wouldn't hold zero. But the new one seems to work fine I can twist the dials and come back to 0 repeatedly have taken it out to 400 meters with my 243. The clicks appear to be out though my testing has shown about 9 mm per click at 100 meters instead of 7.25mm. So have to do a specific drop chart for it which should work out hopefully
