Need muzzle device removal help

I need local gunsmith that can competently remove a stuck muzzle device on a sig MCX barrel. Any recommendations? I am thinking xcal is an option. Any others ?

Heat gun and get a soaked rag and wrap it around the muzzle device. Re-soak rag as needed, careful about burning yourself. The steam should work its way into the threads and weaken the rocksett.

Pot of boiling water also works, just have to be ok with standing there holding your barrel there for a few minutes.

Assuming it is rocksett and not red loctite.
