Hey,
Im new to AR15s as I have just bought my first one.  I took it out and sighted it in and it ran great but im worried I gave too much for it.  I have a postban Colt HBar with a 16 in barrel (no postban comp), removable carry handle.  It has the A2 buttstock, but I think it may be shorter than the standard A2 stock.  I bought it secondhand, but it was almost new; the guy I bought it from told me he had never cleaned it and when I tore it down there was a minimal amount of carbon.  Exterior is near perfect.  It was a cash and carry deal at a show and I gave him $850 for it.  Ive seen similar rifles on the EE here, but none that are exactly the same.  What is the going rate for a rifle like mine?

you didnt get ripped off

new colts run around $1,000

It sounds like a reasonable price for a Colt.

Seems fare enough to me.
