I think I'm going to try my hand at installing a dovetail into my barrel and put one of these sights on one of my muzzies. I was looking at the dovetail cutting fixture made by Wheeler Eng. from Midway USA. Looks easy enough. But I have a question iry n to them to see if it will work for a 15/16" and/or 1" octagonal barrel.
They don't make them anymore ! There is a you tube video on it that's very good I'll find it and let u know.
