I inherited a Remington 572 from my father who received it from a good friend who has since passed. It's in great shape, I'd like to get it out shooting this summer. However, I have a hell of a time seeing the front sight. I would like to get a fibre optic replacement. One gunsmith I spoke too said there was nothing available, but I figure there must be something out there. I'd like to stick to open sights, not really looking for a red dot or scope right now. Thanks for any suggestions.
