John, late back into this thread, but it seems to me that my 24 DL had that Williams peep on it when I got it from my buddy and I assume it was d&t at some point for the installation. The 24 is back home in the safe or I could look at that sight to see if there is a number on it, but I think that it was made specifically for the 24 because the bottom is recessed to mount low to the receiver.
Okay, thank you. Not sure if I want to drill and tap it but will check with a gunsmith and see what my options are. If i’m ever able to find a sight.
I thought about setting it up for a red dot scope but the stamp on the barrel stating not to use the shotgun barrel with a scope changed my mind. Anyway, I appreciate your input.
John
