"Cookie"This has me surprised. Amount of adjustment hadn't come into conversation with my friend who had the FX rings. Here in the UK, the UK wholesaler won't stock FX adjustable rings.....just as they won't stock many other FX products ..... because apparently there is no market.
It was the Sportsmatch's extra screw for fine adjustment that won it for us, as well as price. With them, the furthest distance I have tried to zero a centred scope to is 50 metres; and it never occurred that I should try to max them.
Before using vertically adjustable rings I had great doubts over their ability to keep zero...but that was based upon a friend's poor experience of rings that had both vertical and horizontal adjustment. I have never, at least with air rifles, had a more reliable set of single leg rings than the Sportsmatch vertically adjustables. I have no idea why, but I have knocked and torqued them while slipping and sliding down banks and yet they don't move.
