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.

Hey man, first off just gotta say thank you. This is exactly the type of knowledge I was looking for. I had already decide that my first upgrade would be a new trigger, but I just assumed drop in was the way to go. You def make a good point though, so I might rethink that. I have been looking at shorter barrels. Mainly 10.5". I have heard that anything shorter than 14" with an AR is too short (I forget the reason why. It was either that length was the minimum for desired velocity or accuracy, I forget which).

I just figured I would not be doing a lot of long distance shooting but I might be doing a lot of maneuvering, esp possibly indoors.ive heard that shorter than 7" shoots fireballs, and as cool as that sound, I was thinkn 10.5 seemed like a decent middle ground/starting point.

Thanks again tho. I appreciate the information.

Last heads up: You have to register barrel lengths shorter than 16" with the ATF, it costs $200. You basically let go of some of your constitutional rights to own a short barrel or suppressor or full auto. It's a FED offense (prison time) to get caught with SBR, so consider where you live. However, if you buy a SBR and hide it so that when SHTF then nobody but you will know.

You can register the AR as a "Pistol" AR and use a "brace" and for now, technically, it's legal.

Buy a 16", then if you really like shooting or have a need for anything shorter, then decide what you want to do.

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? Also I live in a good gun state. No extra bullshit for AR pistols unless you make it a SBR.
