Blaser K71 Kipplauf single shot rifle in 7.5x55 Swiss 608 mm (24 inch) barrel with full length rib Engraved alloy receiver, Proof date 1973 I have solved a Blaser scope mounting problem for now. I used two original Sako rings, both intended for the rear of the Sako dual dovetails. The rear Sako ring's recoil lug fits into the semi-circular cut in the Blaser dovetail, so there will not be any splippage of the rings in the dovetails. I filed off the recoil lug on the other Sako rear ring in order to use it as the Blaser front ring. As you probably know, they are windage adjustable and semi quick-detachable. I mounted an older 4X Swarovski scope with a duplex reticle for a perfect low fit, nearly but not quite touching the barrel rib at the front (just enough room to freely slide a sheet of paper), and there is still room to reach the lever at the rear. When I bring the rifle up to the shoulder I am instantly aligned to the scope. So until I find something better, this will do very well. I also took a picture of the rifle disassembled so that you can see how the locking system differs from the current Blaser K77 and K95.
