I agree with everyone.
My Moss 500 has one thing on it. A bead - and that's IT!
Forget all the other junque to confuse the shooting issue even more, or worse yet, get caught on something just as the bad guy has his bead on YOU!
"uhm, excuse me, please don't shoot yet, my shotgun sight is wrapped in my pajama shirt, can we turn on the lights first, then shoot later?"
"Eh, I don't think so, bud - Bang, bye-bye - see you ----- WHEREVER!"
