Regardless of what they tell you, a true optical sight on a shotgun is a great advantage, wingshooting or otherwise. The target and the dot are in the same focal plane and you don't have to take your eye off the target to look for the dot, it's right out there with the target. I shot an old naturally illuminated Weaver Qwik-Point for several years, and it worked great, when it worked. But it was heavy, bulky, usless in the rain, snow, or fog, and I had tons of mount issues. The SpeedBead looked ideal to me; light and handy and small, but I have also heard of mount concerns with them, so I have held off. But I am still tempted. If I could bring myself to tap the receiver, I would get one of the ones that mounts that way, but I can't bring myself to do it to a shotgun.
