Does anyone have any kind of a blueprint for the USGI NM Rear Sight base? I'm going to cut one of my USGI Issue Sight Bases to accept the hooded National Match Apertures, and it might as well be the USGI Dimension, not the dimension that I've found on the various Repro Sight sets, including the SA Inc. ball detent sights. I need to find out how much to mill the cut in the base to accept the hood properly. What I don't want is for someone to go out and measure their rear sight base,which is probably one of the above types of sights, but I'm sure that someone is still going to do that, even after I add this disclaimer. I can do that myself, yet I'm still posting a question on this.
