Hey pto, is that an upper push pin? On a 5.56?? I'm confused.

Yes, it is. I'm confused too.
They probably put it there because they had to cut the cap down in order to be able to assemble the all-in-one lower/stock piece, but it isn't very well thought out, as is now obvious.

I see that. Very odd. What happens if you just leave the pin out?
