Pipe wrench and a new barrel nut. Sucks.

Yup. Had a DPMS .308 i Cerakoted that had to be at 100ft lbs and covered with some ignorant white locktite. Broke the pins off two wrenches with breaker bars then put a 24" pipe wrench and a torch to it. It came loose but the barrel nut was trashed.
Using a reaction rod or a clamp around vise block? Maybe cut the slots deeper into the barrel nut to get the 3 point wrench further back into good material? I think most of the issue is from that damn wrench flexing and tearing up the slots.

Damn. The barrel nut failed before the wrench. Still think heat and a pipe wrench is the best bet. Nut is trashed anyway.

The barrel was super tight inside the upper, might have something to do with it? Who knows.
Anyway, had to get a little snippy with MI customer service in order for them to send me a new barrel nut. I could probably have used this one as the hole works really well but I am sure the integrity is compromised as I beat the piss out of it.

Is that red loctite around the barrel nut threads? If so, somebody needs kicked dead flush in the nuggies. My Radical upper didn't have anything on the threads and came right apart.
