I installed a new front sight on a virgin barrel and wanted to show you how I did it, and the difficulty involved. AR’s aren’t my usual thing, but I learned a trick or two for this job and wanted to pass it on. I drill the sight, ream the holes and install the pins. Use a #31 drill bit to drill the hole then ream it up to size.
