Midway sells a Sako mount that is very similiar to the optilocks it is made by Leupold but it is not the one piece design. It is made for the QD ring set. I have never tried them out but maybe the next time I will purchase them. The one thing they don't offer is thescope protection feature of a liner. Optilocks are very good rings and will not let a scope slip and yet they protect it against ring marks.
