For me, the optics are about seeing the sight clearly, tough at my age, and also to prevent missing because of poor holding under stress and from an awkward position. I’m putting a tiny prism on my .410 SS, and likely a FF3 on the O/U I pick up tomorrow. The .410 is getting a rail, the O/U a rib mount.
I'm curious how you're doing a optic mount on a OU and the model.
