As Lancaster already has posted your photos, I can only add: Yes, you can install these mounts on a Zi-Di rifle 5.6x35R Vierling aka .22 WCF rifle. You have to machine or file dovetail slots into receiver ring and -bridge. I would prefer to file on b at the rear base for fitting. If something goes wrong a replacement rear base can be easily filed from bar stock, the ring not so. But a warning: As I wrote, windage adjustment on this scope-mount combination is only by drifting the bases left/right. This may be time and ammo consuming.
