That front sight is a CZ 550 Magnum front sight that I beat off the donor barrel with a propane torch and a hammer and large screwdriver used as punch.
I cut off the rear of the ramp where I had beaten it, polished and cold-blued the cut end.
Then I hammered it onto the McGowen barrel using J-B Weld as grease.
Patridge insert is from NECG, where you can also get different heights of the original CZ factory bead iinsert.
