The front sight uses the Colt M70 front sight. Everybody makes one. If you have the clean slide GI 1911 now being sold cheap, a low fibre optic sight would be too high for the rear sight, so a matching rear sight is also required. I have installed a number of rear sights on Norcs using the stock dovetail.
I am about to install a low fibre optic on a GI and switch the rear sight to the fixed rear sight off the sport model Norc. It is taller.
Is that .300x 60* for the front? And is that what catalogues refer to as a narrow tenon or a wide tenon?
Thanks
