The Swedes have come up with a fibre optic powered red dot sight for shotguns. It's been on the market apparently since 2017. Does anyone have any experience with one? It seems like an interesting concept, but likely more geared towards bird hunting than tactical use, so I'm not sure how well it would work in that sort of applications.
