question on BCA upper assembly

[tdbru]

well, propane torch didn't crack it loose. so it's in the freezer overnight and tomorrow i'll propane torch the nut again, and use a cheater bar on the wrench. i'll either get the nut lose of destroy something. quite unhappy with how hard BCA put that barrel nut on. no need for that. live and learn.
