Trying to sight in my 1894 Cowboy today. The little adjustment screw for the rear sight broke. Now the gun is useless. I called Marlin. I guess I bought the rifle in 2008. They don't have parts for it anymore. He said they use a different rear sight now. I asked if he could send me one of those. Maybe I'm wrong, but I thought he would just send it to me. It was going to cost over $30. I might put I ghost ring on it from Brownell's or something. On the bright side, my Rossi 92 was shooting real nice.
