What leads to the need for the negative sear engagement?

How much is it (angle?)

Is this because of the potential for "bounce" of the slide when it comes back into battery after firing a shot? Or is it needed to draw the sear and firing pin together when it comes into battery?

Why is the single stage AR-15 designed with this engagement?

I think a description of the thinking behind the negative sear engagement would make a good FAQ entry... Marc

Ray, if you can get higher resolution scans of the article to me, I'll make it into a PDF file.
