I was wondering if someone has taken parts off of a carbon fiber ar-15 and used them on a mil spec (aluminum) ar-15. In other words, will the uppers interchange with the lowers? Thanks

The uppers and lowers WILL interchange yes. They WILL fire yes.

The thing is personally I don't much trust carbon fiber and/or polymer receivers for ARs yet. I had a pre-Bushmaster carbon AR rifle and the lower receiver broke at the rear where you screw in the stock. Had a crack half way through the receiver. That was only after 5,000 or so rounds.

Would they work as say an average hunter's rifle? I believe so - just don't plan on putting a lot of rounds through it.
