So upon installing my new receiver, I had to remove the steel nut on the buffer tube. After an hour of extreme torquing and holding in a flame for several minutes before being immersed in liquid nitrogen and the process being repeated. I even tried freezing it in liquid nitrogen and smashing it on concrete to no avail. I finally resorted to dremelling it off with a metal cutting disk and after breaking through it actually popped showing how stuck on it was.
