That's called a 'tang sight' and is pretty commonly used for longer ranges. It really can't be used with the bbl buckhorn because you can't see past the buckhorn thru the tang site. It just gives you a smaller peep type site for better accuracy and a longer sight radius. I use it all the time on my other one. I have quite a few old style rifles ...some new mfg., some old. I took the bbl buckhorn off this one. For shorter range I just basically point shoot by looking down the bbl at the front site...that works fine up to about 50 yd.
