Agree, but I cannot think of one negative in doing it. However, dulling the teeth like edges may result in something positive. I don't think I'm removing enough to really move he CC's of the chamber.
Too bad they didn't cut a face into it.
Maybe it would be a good idea to get the grinder out and remove material on each side , open face plug recess, just a enough not too much. But if it ain't broke... dont fix it I guess.
The small recess behind the threads bugs me though.
