A friend sent some vid links for the HM DEfense mono block barrel and Battle Ready Bolt.

The argument for accuracy seems to be sound regarding accuracy but as we know, real world results often vary. Does anyone have any experience with this barrel and thoughts on accuracy and barrel harmonica?

It seems that the bolt would be significantly stronger. That will probably never impact me since I’m not a high volume shooter. Are you seeing a potential benefit from this bolt design other than extended life?
