Hello, i was hoping somebody could help me fix a tang sight problem. I have a savage 1899 that was built in 1899. It has what i beleive is the original tang sight on it as it has no markings. The problem is the knurled nut that moves the stem up and down is a little loose on its bushing and moves up and down causing the elevation to change sometimes. You guys have been great in the past when i had a question and i want to thank you all for your advice. Cherryfarmer
