Best sight for a shotgun?

[Armorer 101]

My guns all have the smallest bead made, on them. Hunted doves in Argentina for 10 days without a bead and never noticed it had come off until one evening when I was cleaning the Beretta 391. I had a bird boy cleaning my guns until the last day. If the gun fits you, you do not need a bead at all. If the gun does not fit you, the biggest bead will not help you.

The vent rib is there to cool the barrel and prevent distortion from heat waves that occur with a plain barrel.

Got it.
Can't have all those heat waves distorting your sight picture!
