Mount FastFire to vent rib or other solution?

[chode2235]

Im trying to get my new 20 ga Franchi Affinity set up, and am looking at potentially adding a red dot like a Fast Fire III.  This will be my wife's upland gun as well, so I will need something that can be easily removed, is there a mount that I can use to mount the red dot to my vent rib or some other sort of mount? 

Or are there other options besides the drill and tap?

If there is a speed bead mount to fit the Franchi, then that would be ideal. You could just leave it on for your wife to use on upland birds.

I agree.  It would be great if they made a speed bead for a 20 ga.
