Rear Sight Question

[peterbh]

I have most of my parts on hand but not a rear site. In looking throughWeil's Contemporary Makers Of Muzzle Loading Firearms, Bivins rear sight is SO cool in both artistic design and pragmatism with fixed blade and one pop-up blade for longer range. Does anyone make anything like this?

Track of the Wolf and Muzzleloader Builders Supply have folding leaf sights.

I have used several of them, don't like them & ended up welding them up or swapping them out. They do look neat, but keeping the flip part up & tight is not as easy as it sounds unless you have a spring mechanism under it or something. I think the last one I did on a Jaeger of mine I took the flip blade off & just use the bottom part.
Mine came from TOW, I think MBS has them as well, as mentioned above.
