My 16" Rossi .45 Colt shot way high with factory duplication loads. I went with the Marble Folding Sporting Rear Sight No. 95, Brownell's Stock No. 579-000-082 and the Marbles 50W front sight, Brownells, part # 579-105-031. The latter is a .500 tall front sight, with a 1/16" gold bead and the oddball dovetail base that fits these rifles. Yours might need a different front sight to make it zero.
