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?
My problem lies in reconciling my gross habits with my net income.

Rob:
While the sight could be fit by measuring the two dovetails with rolls and doing the math, it is not really necessary.
I assume your new sight is close to the correct size. Pick one side of the dovetail on the sight and file it at a very slight angle so as to make it tighter as it goes in. You really don't need the wedging angle, but ever so slight of one will prevent the opposite angle, where it gets looser as it goes in.
You can use a magic marker to color the metal as you file, to be sure that you are cutting where you wish to. Just go slowly and carefully until the sight will start into the dovetail on the barrel. Reinking with the marker will show where the interference is. Take another stroke of the file and try again.
Ultimately you want it to tap into place. The key is to find the happy place between a beat it in fit and a slide it though and fall out the other side fit. It is not difficult if you are patient.
Best of luck.

Good advice!
Also, lightly dub off the sharp edges of the male dovetail.
I file a small flat on the bottom of my brass drift to sit on the bottom of the dovetail.

Gentlemen,
After you fit the rear sight do you usually reblue the filed side?
