I need some advice PLEASE

HI All,
Here is the deal, here a few weeks ago I traded for a Sweet looking Pre Ban Colt AR 15, the problem is the guy that bought it new changed the barrel and bolt. The lower is marked 7.62x39, and it has a Colt 20" H Bar5.56 barrel and a Bolt. Every part is Colt and the only thing they change was the barrel, gas tube, and bolt. The BC is 7.62 Colt but it works great for the 5.56. If I was keeping this gun it wouldn't matter.
If I leave it the way it is, How hard is it to sell?
Do you all think I could hunt down a Colt 7.62 barrel and bolt? I have owned a lot of AR and have built several, but there is something about a Colt and it isn't the name, I cannot explain it.
I wait to here from you all. (What to Do?)
Thank you all for taking the time to read this.
Greg

So, it's not a complete 5.56 upper?

If you are going to shoot 5.56 put the right bolt in it.
Colt 7.62 upper are pretty hard to find, they pop up once in a while but not very often.

What I was told, was the guy swapped the barrel and bolt.I looked at a Colt 7.62 AR and the BC that is in the one I looked at, mine look's just like the one in the other gun. 7.62x39 BC looks differnt than a AR 15 or a M16. I have not head spaced it but I am going to in the morning.
