I see flip to side magnifiers, , but never optics. I'm assuming the challenge is holding zero. But it seems that a quality manufacturer could come up with something that would index itself with a QD type of attachment as a hold. While I like the concept of QD red dots, if I ever needed to remove it and use iron sights I wouldn't want to have to necessarily drop it, carry it, or stow it away. I wish they just had a QD mount that when loosen would flip to the side (think canted position) and stay on the rifle. Maybe it exists, and I haven't seen it...thoughts?
