- The front sight sides were cut with a radiused end mill (first pic)

- Nambu receiver/barrel extension has a 2.5mm x 8mm flat milled next to barrel shoulder for alignment purposes (second pic)

- 120º chamfer cutter used to cut feed ramp

- 40º Harvey dovetail cutter used for front sight blade; 60º dovetail cutter used for rear sight base

- The Luger artillery rear sight sits higher than the original grip-frame Nambu rear sight, so milling the Nambu rear sight off was not necessary
