cmshoot would you use an aero or BCM upper?
I have a very good opinion of Aero receivers after building on them for folks these last few years, but they ain’t BCM. Go with BCM.

The only time you use anti walk pins is if you use a pre maid drop in trigger. On a standard trigger it's the springs that holds the pins in. With a drop in trigger unit there are no springs to retain the pins. You must use anti walk pins in that situation but those anti walk pins are included with the trigger most of the time.
Thanks for the help guys!
I strongly suggest you look into Knights Armament. Affordable, easy to get and the best finishes on any rifle out there.
I’ve got a BCM 300bo 9” upper and it’s very nice quality!!!! My 2 cents input …..
I dont have a problem with Aero receivers at all. The only problem I have is they are too expensive on their website. You can get them much cheaper at other retailers. They make for a solid foundation. I don't use anything else from them except maybe gas tubes. I used a set of their M5 AR-10 receivers and I am impressed with those. I have used maybe three sets over the years but the only set I have now is on my AR-10 in 308. Nothing wrong with those at all. My only gripe is their prices. They went up exponentially over the last few years.
I usually weld my AR triggers into place. They don’t move at all. Very secure.
Fellas, I gotta tell you, building an AR is a deeper rabbit hole than any conspiracy theory I’ve ever looked into
You laid it out on ODT, what the **** did you expect?
Some simple guidance....
Instead I got a history lesson on PSA when I wasn't even looking at 1 of their parts for this build...
But none the less I like to learn so it was good!
