What type of flash hider is it? Was this upper being previously used with a suppressor? I have heard others say that if you submerge the flash hider in boiling water it will loosen the Rocksett and penetrate to the threads. I would think that low gradual heat would work as well.

Submerge it in water for 24hrs or more, just room temp water is fine. Then try and loosen it, it'll come free.

I have removed several Rocksett'd M4-2000 flash hiders and have never soaked them or done anything special to get them off. Just the wrench with a little extra force and they all came right off. Rocksett is not an adhesive, it is just a thread locker like Locktite only Rocksett doesn't breakdown at high temperature like Locktite does. The temperature resistance is why they use it for suppressor mounts (which get quite hot). YMMV

I don't doubt that water would help break it down.
I was simply relating my experience with Rocksett'd flash hiders. Perhaps the barrels you had were not only Rocksett'd, but over torqued as well. I have seen folks bust teeth off of a barrel nut that had nothing on the threads. The flash hiders are not normally installed so tight. Anyway, that has been my experience, YMMV.
Gotcha. The water is really needed when whoever put it together used way too much.
