OK. Just a bit of a resource tool here because a few said they were following my experience. I am by no means an expert on the issue, so when someone finds a mistake, please let me know and I will change.
If you plan on getting an ar-15, build it yourself. You get to pick out the parts and put it together. It doesn't take long and honestly, if you like doing things with your hands, you would find this satisfying.
At the end of the day, you can put it together and say you did that. Now, I am only talking about the lower receiver. I haven't played around with an upper receiver.
Anyway, with the advent of the internet, you can find dozens of reviews on just about any part you are going to put in your gun.
You need to buy a stripped lower to begin with. That is only a piece of metal milled to the specs to hold all the pieces. They are pretty much all alike. I bought a Stag lower, and I believe they make their own, but otherwise only about 4 people make all the lowers, they just have different names.
You need to purchase a lower parts kit then. Many people make them. I went with the daniel defense kit because many of the reviews liked the trigger on that one. Now you can always do a number of trigger tricks to improve the trigger or put a whole new trigger in. Lots of options.
As everyone says, an AR is like a lego set.
OK, you have your stripped lower and your lower parts kit. You need to buy yourself a stock. I threw on a bushmaster 6 position stock but there are cheaper options.
That is about all you need to put together a stripped lower. You then purchase yourself a complete upper and you will be good to go.
Let me include a couple of resources here that I used... LINK
This is the installation guide from AR15.com. I found this helpful.
Also a couple of videos to help out... LINK LINK
Honestly, that is about it. Picking out your parts will take the most time. You can get all these parts shipped to you, but if you do, you will have to have the shipped lower shipped to an ffl.
I bought all my parts from LINK
All the parts I needed together on one site with great prices to boot. You can find other sites though that have good prices. Lots of people talk about Buds.
Now you can always buy a kit from someone like delton or model 1, but I wanted to pick out parts for it myself. If you are going to build, you might as well get the full effect.
Any other links or suggestions to leave for people might also be left on here for people.
