Smylee and Dave.
How about a little more info on that last photo, and maybe a photo or 2 of the process?
I'd guess that you drill that hole prior to shaping the sight, then shape and cut??? That correct?
That's a good, "lookin sight"
with that thin contrasting line, AND it will take the abuse of a normal iron sight.
Don't hurt the "looks"
of the rifle either!!
