MAK mounts are often sold by Frankonia and Ketner when they sell Blaser rifles as a complete outfit.
I also have MAK mounts, bought from Mulliner Guns of Wimbourne, and as regards quality they are as good, if not better than the Original Blaser mounts.
The Bulgarian ones have the edge, as they have more slots to mount your rings forward or back on the 'scope.
One of the slots can just be seen in picture two of my previous post.
I have my front scope ring as far forward as possible and the slot, to allow me to bring it back if I wanted to, can just be seen.
