There’s a “how to” on gohunt.com you need a rear peep, I went with the “ace in the hole” which is a integrated rail peep, then you need a front ramp with a dovetail for the Lyman front globe to slide in, then a Lee Shaver sight card (it’s a collection of sight options that fit in the Lyman globe) the problem that a lot of people have is the Lyman doesn’t fit right in the ramp and homemade shins are required. Another issue is the availability of the parts. I had to buy each part from a different vendor. Brownells, midway, Natchez...I think? The gohunt article has the part numbers and ordering info. I searched and searched for a one piece front ramp/globe but couldn’t find one. Hope that helps, it’s a good option but not perfect, much more precise that factory sight.
