I have one I shoot and the sights work very well for me on it, even with my bad eyes. My 1816 Harpers Ferry. The sights are very easy to use or I should say sight. They only have a front one
Very simple concept..
I did hit a 2 x2 foot board with the Old Gal at 100 yards one day just for a giggle..
I did put a little white paint on the front sight of the Trapdoor. It helped a little but not alot..
I may try some Black once. I looked at using trailboss. But isnt that a real slow burning powder? Thanks
