I dont think you can rechamber them easily. Its probably cheaper just to buy a new upper. If you have a PRE-BAN gun you can put a preban upper on it. But it (your original gun) must have been assembled into a COMPLETE gun BEFORE the ban. If it was just buy a new 5.56 pre ban upper.

A new barrel and a new bolt will be required.... You will need a barrel wrench and a receiver block and insert to clamp the receiver down. If you don't you may warp the receiver.... The upper is worth $450 to $500 (maybe more depending on condition)with the BC and you would be able to move it fairly easy on AR15.com or the strumgewehr board. Then you could get a factory assembled upper for that price and not fork out the cash for the tools... Good luck.. [url]oldedantucker@hotmail.com[/url]

I'd sell the 7.62 x 39 upper and use the money to buy a new 5.56 upper. As pickupdan said, you can get a nice new factory upper for that price and not have to mess around with buying tools and possibly buggering up the assembly.
