Anyone have any experience with 308 uppers halves on ar-15 lower recievers?

So far I've only found one source for 308 upper halves. There must be more...

Does the 308 barrel, nut, bolt and carrier fit in a standard 223 upper reciever, or must we use a 308 specific upper reciever?

Thanks in advance for your help.

No.  No one has experience with this.  It won't work.

 Again, no.  See answer above.

The .308 NATO wil not fit through an AR-15 lower mag well.  At least not at any angle that would allow feeding out of a magazine into the chamber.  You have to go with an AR10 lower.

I'm new to this and am currently looking at assembling an AR15. This is an item of great interest to me. I've seen a lot of uppers in different configurations and wondered about a .308 upper on a .223 lower as well.

Is is possible to have a AR10 lower that could accept (and chamber and fire, of course) a .223 upper. Probablly too good to be true, but man how sweet that would be.

Olympic is making uppers base on the WSSM (Winchester Super Short Magnum) case.  There is another topic I started here just a couple of threads down and one over on AR Discussions.
