I did one of the first before Badger Ridge took over sales. I bought directly from "Hunter" on Doug's Message Boards forum and installed it myself. As I understand they've made a minor change to the firing pin since I did mine, but it works great. If Ruger would have made the 77/50 with that setup from the start, they'd still be selling them.
Was trying to find a SS m77 for sale and by the time you add the cost plus this modification you can almost buy a new Remington Muzzleloader. If I owned a Ruger muzzleloader I would send it to those guys for that mod
