Continuing to machine the front sight blade in place...
Blade height fixed & milled; squared off front sight blade; milling the 'ramp' on the blade.
Second set of pics is the finished faux front sight blade. I set the height of the front blade equal to the height of the rear sight, as that is how my Luger artillery rear/front sights measure up. I assembled some of the special tools I had to make for this project. Finally, a shot of the barrel being torqued in place in the Nambu receiver [barrel extension], using three of the special tools.
