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.

Twist ratio is the "rifling" on the barrel. The rate at which the grooves are cut. Puts the spin on the bullet.

1:7 used to be pretty much standard because it was military default. Heavier bullets. 1:8 covers I would say the largest range of bullet weight. Best middle ground. 1:9 for lighter bullets.

I have found that 1:8 does everything pretty well if you're not competition shooting. It will stabilize 55 Grain Vmax varmit pretty darn good out to 100-200 yards, and those are pretty light bullets.

As for ARs and Cars: you pay for the brand. You can do any number of mods to a decent frame on a car and that will make the car "better/faster".

Colts (larger receiver pins) are assembly slightly better than Bushmasters, but who gives a shit. If you like colt and it shoots great, then shoot it!! If you want to save money and say you built it, then shoot it!! An barrel can only shoot as good as the person shooting.
