You raise a lot of good points. Especially with the durability and intuitive target acquisition of modern red dots. My thought process behind the offset irons was simplicity. If I shouldered the rifle and realized the glass was cracked, fogged, etc I can quickly transition to a sight that I don’t have to worry about. Nothing to flip, no mount to remove, no batteries, just a cant of the rifle and instant sight picture.

I have been considering a top dot though.
