It's kind of a chore, but here's how I rigged up my sight. I removed the front sight and got a williams shotgun sight base. It is dove tailed and will accept a williams firesite. To get the right height, I made fork shaped piece of wire and taped it to the barrel in place of the front sight. Next I bent the handle of the fork up to make a sight post. Then you just go to the range with a pair of side cutters the trim the wire down until its the right height. Measure it and call williams, they can get you fixed with the right combination. You will have to enlarge the screw hole from a #4 screw to a #6. Paid a gunsmith to do this....a man's got to know his limitations.
