What is your favorite part on your AR?

[circuit]

Mine would have to be my CMC flat trigger. Although I would like to get a geissele trigger, the clean crisp break and I don't know just the way the flat surface feels, I love it. So just wondering what is everyone else's favorite part on their guns?

I'm pretty fond of my Noveske stainless barrels.
I love my Wilson TTUs too.
Actually, pretty much every part on my rifles I love. Even my KNS takedown detents, lol.
I don't feel much for my castle nuts - nothin' real exciting about them.

Yeah it took me some time to come up with one particular thing.
