The factory sight is orange Dan. I'd like to get a firesight type rear sight.Have you tried painting the front sight? Try different colors see which works best, orange, yellow, sky blue whatever. As I recall that rifle has a thick white front sight bead. I replaced one with a smaller brass looking bead sight then painted orange. Worked for me. Dan.
That Lyman Deerstalker is made by Investarms, who also makes the other Hawken-style rifles for Lyman, Cabela's, etc. It is a very near clone of the TC Hawken, and measures 15/16" across the flats. The Williams sight for the TC Hawken will fit with no problems, as will most any other sight. Tang-mounted sights will require gunsmithing, tho.
Called Lyman. They believe it would fit.Williams offers this for the T-C muzzle loaders, I didn't see one specifically for the Lyman Deerstalker, but perhaps it would fit?
Also looked at Lyman's web site and found a photo of a fire-sight rear sight for a muzzle loader, but no product number or price for that particular sight. Perhaps a call to Lyman would be a good place to start?
This is what I bought for my Hawken.I'm trying to find it in stock. If anyone see's that available please let me know. Thanks!
