Basics: What do you want it for? Home Defense, plinking, competition (Hi-power, 3-Gun, Long range, etc.), to be Tacticool, varmint hunting, big game hunting, etc. You can say yes or no to each category which will narrow the choices somewhat.
Options: What is most important? Accuracy, reliability, optics, ergonomics, modularity, etc. Again, each category can be yes or no again narrowing choices.
Caliber/Chamber: .223/5.56/.223 Wylde are the three common chamberings in the AR-15 platform, the .223 Wylde having the best overall appeal. I'd suggest no wilcats or .308 for a first AR.
$$$: What is your budget, and does it include magazines, optics, etc.
There are some great, Above average, average and poor quality parts. Also, there are some slight differences in what some companies call "Mil-Spec" and there are some parts that can be MS or Commercial. There are also small pin and large pin, so just picking a bunch of random parts does not guarantee compatability.
Great: Firebird Precision and JP Rifles (1500-3000 for a comlete rifle)
Above Average: Sabre, RRA, LaRue (800 to 2500 for a complete rifle)
Average: DPMS, Armalite, FN (700 to 1500 for a complete rifle)
The Sabres are pretty tough to beat for an economical all-around first AR.
