I haven't been shooting my AR(s) lately nearly as much as I used to. However, this video brought back a lot of memories and similar experiences when I first got into ARs. So hopefully this video and ensuing (hopefully intelligent) discussion will help some who are thinking about getting into ARs.
I watch many T-Rex Arms videos on gear mostly because they try a variety, shoot them alot, and share what they like or don't like. They also include more of their staff and friends/guests for a variety of perspectives, vice just Lucas. I don't agree with everything they say, but they do spend a lot of time and energy trying, testing, etc via shooting. I very much appreciate the try for yourself approach, which I spent a lot of money on my own to prioritizing value for my AR setup(s). I very much appreciate that they have similar shooting disciplines/interests in competition, defensive, etc.
I am very much a fan of BCM uppers and have a few of them. I have one Aero lower and I think it's just fine, but lowers are lowers (assuming starting with a quality one). I've tried higher dollar uppers and have sold most of them. I haven't shot nearly the quantity of rounds that this group has, but I've shot out a couple of uppers and have done many side-by-side testing, like Gov't profile vs lightweight barrels, cold hammer forged vs plain chrome lined vs cheaper/budget, etc. I have a couple of PSA uppers and they've all shot fine for me, even out to 300 yards (but minute of 12" x 18" plate).
My favorite setup is a Colt 14.5 with BCM rail, Colt lower with Geissele, EoTech EXPS, and Surefire light. So some similarities and many different "toppings" from what Brandon featured, but different contexts. Plus no suppressors in HI
