Findin an adj f/o sight to put on a NEF 10 ga that will mount to existing holes. Thnx for any info.
I have never heard of anyone finding a set of sights with the correct hole spacing.
I believe the holes are predrilled for a scope mount.
I saw one example where the guy used a CVA muzzleloader sight, attached it with one existing hole and then drilled and tapped the second hole.
