Advice on aperture sight for TC Hawken

[Confederate rifleman]

I have this sight on 2 rifles. My Hawken and Renegade. They fit, are rugged and work quite well. They're best as a zero and leave it sight due to the lack of repeatable adjustment for windage. If you're fortunate enough to have a rifle that drops multiple loads on the same vertical line ( like my Hawken) then the windage concern is a non issue.
A TC sight on a TC rifle is a nice package.
