I have an aero precision stripped lower that I am building up right now. I am trying to decide what brand I should look at for uppers or full build kits to complete it. From the looking I have done it is most likely between PSA and BCA. So if anyone has any advice on which to pick or other suggestions, I am all ears. I am looking to make a cheaper gun but not a piece of shit gun. I was also looking at Ceratac, if anyone has had any experience w. them. I've dealt with their customer service just to ask questions and they were very helpful but they're extremely cheap so I get worried. So any help would be appreciated. Sorry for the wall of text.

TL/DR: I'm building an AR15 and need to buy a cheap(yet somewhat reliable) brand complete upper receiver, any suggestions, advice, warnings, or otherwise relevant information is welcomed and will be appreciated.

I guess I'm kinda a dickhead for not just starting there. Lol. But thank you. Appreciate it.

Lots of information online about ARs but you got a solid summary here. Your configuration ultimately depends on your projected use. A basic personal defence weapon doesn't have to be complex or expensive.

Im about to post pretty much the same post to you as I did to protodonata, so please dont be offended. It's just for sake of ease. And I want both of yals input if possible. Thank you. Sorry for the late response. I haven't been on here at all. I have another ? For you if it's ok. I was looking at a kit on PSA. https://palmettostatearmory.com/psa-10-5-5-56-nato-1-7-nitride-9-m-lok-moe-ept-sba3-pistol-kit.html This one. And in the comments someone asks if it will work with a piston kit. The answer given was " no, it's a DI assembled upper". What does that mean? Lol. Also I'm about to pull the trigger and but this kit. Thoughts? Good? Good enough? (I know it's 1/7, but from my understanding I can just upgrade the barrel later if I want) Also I live in a good gun state. No extra bullshit for AR pistols unless you make it a SBR.
