Sportsmatch AOP55 is completelt adjustable mount for windage and elevation. But it has a weak link. The tiny grub screws used for windage adjustment that holds the other part of the mount, are made of mild Steel while the mount is made of Aluminium. The area where these grub screws enter and hold the aluminium, has very thin walls. When these grub screws are tightened fully, the aluminium get out of shape and the mount does not hold zero.
To resolve this issue I got the aluminium part made out of Mild Steel and kept the thickness of metal a bit more than standard.
This helped me use this mount with scuccess.
Just sharing it as some may benefit from it.
