Recknagel made Tip-off rings for the Steyr SSG 69. I actually found a 30mm set in one of my boxes of bits. I have a feeling there is another larger set some were if my memory serves me right.
So there you go I have several options open to me now. Moral of the story dont ever throw any thing out when it comes to shooting hoard stuff.

hmm whats next. Go shoot the SSG with the new nightforce scope.
