Williams Fire Sights for Franchi Affinity 20g compact?

[Coop1082]

Fell into a sweet deal on a compact Franchi Affinity compact 20 gauge. I can't find the vent rib width anywhere online or in the manual. Curious as to if anyone has installed the Universal Williams Fire Sights on one? Run them on my BPS 12 and they work like a charm. Thanks for the help in advance guys.

I beleive they will work as it is universal.  You can call them and they will let you know for sure. I called them eariler this week and orderd a set with rhe dront sight green and the back red.

They fit fine.

I certainly hope so because the 6mm gobble dot I've seen quite of people recommend didn't end come close. It just came in today and with the plastic inserts it won't even fit on the rib. Remove the plastic and add the rubber shims they sent (both of them) and it's way too loose. Have some fire sights on the way and really hope for a better fit. The rib on a tape across the top measures right at a 1/4" so fingers crossed.
