I already have a stripped upper and lower, built, with Gunfighter charging handle. It doesn't have a trigger assembly, or a BCG (pic of the starting-point parts at the bottom of this post). I'll use the Geissele ACT and BCM BCG, as per the spec. Those are included in my parts list. My parts list comes to $1,199.30. That doesn't include shipping of said parts, it doesn't include "Disruptive Grey" Cerakote, and it doesn't include a light setup - I'll use my preferred light setup if I can't find this specific light. Cheaper? Hell yeah, it will be. Some of my parts that I've picked are a little bit better, too. We'll see how this turns out, because I'm doing it. Pic of what I've already got on-hand is below:
