My Winchester 1885 Low Wall 22LR came with a Marbles small tang sight.   

I wanted to be able to adjust the elevation with high fidelity during the match.  Also the black cross hairs and black peep sight on a black animal did not work for me. 

So I installed  a Lee Shaver Economy Mid Range Soule rear sight and a Skinner tall brass sight on the front.  Still playing with how I might improve the sight picture.   Hoping it will improve my scores.
