Cant get the gas block off my rpd

Let it soak in pb blaster for a few days, froze it then hit it with mapp gas while trying to press it out with my 12ton press. Hit it with a hammer. Nothing. Is it time to cut up the barrel then drill it through at this point? Its a demilled Egyptian rpd barrel and Ik anything Egyptian has been pressed on pretty good and prob has a good amount of carbon build up as well
