I can remember when this "mod" was given birth on ARFcom many years back. I guess it might have value if you're perpetually changing your end plate for some reason.

This is a very useful mod on the older KAC lowers with the extra QD points. They were designed so that the pistol grip retained the take down pin spring instead of the end plate. There were a lot of issues using grips other than the A2. The setscrew fixed the problem.
Oh... don't get me started on KAC's nonsense. Yeah... I had to fix some of those problemos on Pappabear's KAC. It's gone now.
Unnecessary as it may be, I don't know that I would be compelled to remove it now if the rifle is functioning properly. And if all manufacturers started threading the detent hole, nothing stops you from installing the detent and spring the normal way.
