What's my first decision then?

A good starting point is to consider for what you want to use the rifle. Long distance "tack driver" or for a short-range metal-plate competition run-and-gun, shoot-and-move CQB type of application? First thing to get in mind is what "barrel profile" you want. A heavy Varmint style, a Lightweight, and M4, an E2, a CAR, XM or Commando? Then barrel length. Do you want a standard A2 style "carry handle" built into the upper receiver, or did you want an A4 "flat-top" with a Picatinny Rail built into the upper (to which you mount optics or flip up iron sights, etc)?
