I am fitting the proper rear sight to a vintage Remington M14. The proper sight has a wheeled elevator, I am replacing the blank in the dovetail slot.
The new sight will not start in the barrel dovetail (I am installing from right to left) so I have to file the sight. I have the proper file, 60 degrees and two sides safe.
I imagine the proper procedure is to measure slot in the barrel and file the sight. Should the sight be tapered to allow it to wedge in or should I file it as close to the width of slot as possible and keep the edges parallel? How many .001's tolerance is OK to keep the dovetail from moving?
