I'd like some recommedations to replace the sights on my Kibler Southern Mountain Rifle. I don't care so much about authenticity as I care about functionality. The rifle shoots really, really low (like 12 inches low at 100 yds) and already I've tried upping the loads, and I've also filed down the front sight a couple millimeters. I think I'd have to file the front sight to a nubben, and it's already too damn small to start out with, anyway. A rear sight with adjustable elevation would be a real help, as well as would an iron front sight with a heavier blade, driftable for windage would be OK. Your recommendations for replacements that would preferably fit in the existing dovetail cuts would be appreciated. TIA.
