For sale. Sako Stainless Optilock 30mm Low Rings and Short Action Bases. Very good used condition, came off a .223 Sako 75 that has moved to a new home . The plastic inserts are perfect but the ring screws are blued as the originals were a bit rounded off in the allen socket by a slightly undersize allen key so I replaced with new blued ones. RRP on rings is around £85 and RRP on short action bases is another £65 so shall we say £85 posted.
