I would love to see a breakdown of that, with prices, and links.
Mid length 16" as the configuration, please.
I built my AR pre-panic and it cost over $1400, and it only had a standard trigger group.
Daniel Defense 16" barrel
Daniel Defense upper
Daniel Defense BCG
Midwest Industries quad rail
Armalite lower
PSA LPK
Magpul ACS stock
Can't imagine building a whole rifle with Geissele trigger group for under $1200.
BTW most of those PSA uppers which are under $600 come without a BCG or charging handle....so add another $200
