What configuration your personal AR ends up in is, well, personal.
The popularity of them has given rise to congfigurations that didn't exist when I started.
AIM Surplus is selling an upper that I wish had been around when I built my first one.
Here are some pictures from their web site.

That's a dissipater configuration with the gas port in the mid-length position instead of the more "traditional" carbine location.
I've long felt that if you have to have a 16" barrel then a middy is the gas-system to run. What a dissy gets you is a rifle's sight radius and longer handguards. You lose the ability to mount a normal bayonet, but it's the lug that freaks the antis out, and it's still present.
