I need a Trapdoor carbine front sight blade, or two. I bought a Trapdoor carbine and it shoots 2.5 feet high at 100 yards with my Trapdoor load. I would like to buy a couple of reproduction or real TALL front sight blade that I can file down to the right height to get the carbine to shoot dead on at 100yds using the rear sight all the way down ( battle sight) . It looks like there is just a pin holding the blade in place that I could drift out and replace it with the taller one. Has anyone else done this? Does anyone know where to get the taller front sight blade?
