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.

Solid information above. Wylde chamber, 1:8 twist, trigger upgrade, and sights that work for your application. I like to float my barrel but unless you are interested in varmint hunting or benchrest competition floating is probably not worth it. I've never used a gas piston but people I shoot with have never complained about theirs and I've never had problems with my standard system. I suspect it would be hard to find a combination of AR parts that would result in a crap gun. Manufacturers have know what it takes to make good AR parts cheaply.

Everything I have been looking at has been floating. I'd be lying if I said that I didnt think it looked better and that I didnt care about looks. Looks are a minimal consideration but definitely still a consideration. Thank you very much for your input tho. Any thoughts on caliber to go with? I originally was going to go with. 223 to save money on ammo but lately I've been thinkn I'll just get a 5.56, and figure out what I wanna shoot later.

The .223 Remington and 5.56x45 NATO are basically the same. The Wylde chamber allows you to get the best benefit of both. The NATO is cheap and plentiful. The .223 is more likely to be loaded for bench or varmint shooters. Go with the Wylde and feed it either.

Good to know. This may be a stupid question, but so .223 wylde will shoot both .223 and .556? That is what I thought but just double checking. For some reason it is always labeled as .223 wylde and not just wylde or .556 wylde. Also I have heard that if chambered to shoot .556 then putting .223 through it is no problem, but not the other way around. Is that so? And if that is the case, then what would be the difference between .223 wylde and .555 NATO? Sorry for all the questions. I really do sppreciate the help.
