I've seen that Third Eye have started making rings / mounts for Sako 85's. The ones I've seen are one piece (as opposed to Optilocks which comprise a seperate base and ring) and are made from aluminium (with steel bolts). They seem to have the taper required to fit on the action of a Sako without the need for a weaver or picatinny rail. Cost is about £120, which is about the same as a set of Optilock bases and rings.
Has anyone used the Third Eye rings / mounts and if so, are they any good.
