A Leupold base for the A7, if made, would certainly not be the same as other Sako ones, as Sako makes rings for most all their other rifle models and this particular model has an integral Weaver type base, needing ONLY rings to mount a scope. There are, of course, Sako rings made to fit this type of base, being Sako Weaver type rings.
Leupold's site shows no bases made to fit the integral base already there.
