After a lot of research, in no small part thanks to this site, I have decided to build an AR. Before I do this I wanted to talk to you guys as you seem pretty knowledgeable. So here it goes:

Okay, good start.

A receiver is a receiver is a receiver. I've said it a thousand times. Unless you are going to buy Billet, the receiver itself is just a piece of aluminum that holds all the operating parts in close formation.
Billet - The best & most expensive.
Forged & Cast - 2nd and 3rd, in that order. Both will treat you just fine because you are building on them and not buying the name brand with their chosen components. Pick one that fits your needs.

What are you looking to do with it? Besides "defend against zombies" because there are a ton of answers to that question, like distance to target, area of conflict, indoor, outdoor, both? Alot of these answers are going to be based on what the end goal is.
You want a 600 yard varmint style weapon with a 20" bull barrel that weighs 13 pounds but will shoot 1 MOA that you don't mind cleaning and maintaining properly? You are looking at a Kreiger or similar product.
You want a 150 yard gun capable of hitting man sized targets in an urban battlefield setting like Somalia? Where you can shoot any type of ammo that you can find and aren't afraid to go a day or two without cleaning it?
You are looking for a standard G.I. profile, chrome lined barrel, which is about the most common one out there.

This is going to depend on what rifle you end up building. If you are building a SHTF gun, then military ball ammo is going to be the most common and easy to find.

Check out the threads at the top of this section, that is a great place to start.

This can't be answered.

The parts are about 10% of the equation. If you don't know what you are doing behind the trigger and maintaining the rifle Dave Lauck could build you a custom gun, blessed by Eugene Stoner himself, and it's not going to help you in 6 months of abuse.

My definition of accurate and yours will be greatly different, of that I can assure you.

Yes. This is the key feature of the AR-15 platform. You build one upper for range and one upper for clearing rooms.

Stop reading advice from other websites that claim the AR is going to jam on you and leave you dead in a ditch.
Know your weapon. That will cut down on a lot of Internet-Mythos.

Building your own weapon will ensure this, but you have a cart before the horse issue.

Slap whoever wrote that and put it in print. All ammo eventually drops. On a long enough timeline, or range, everything designed failed.

How good of a shot are you?

Just one based on the barrel, except for the .22lr which can be fired out of the .223/5.56mm with a chamber/BCG conversion.
Different uppers can be built in about 100 different calibers, but they are not universal as one upper.

Yes. Twist rate will determine what grain bullet you end up shooting. Some twist rates are good to handle multiple grains, but every twist rate and every barrel has a "sweet spot" where one type of load that is ideal for that barrel.

Facepalm. No. There is absolutely ZERO truth to that myth. Whoever told you that doesn't know the modern design.
And this is absolutely
THE LAST TIME I will answer a question this broad.
