That’s a pretty jacked up beginning or end of thread. That being said does the barrel thread into the receiver, barrel nut, whichever, does it bind up?wuth ad many years (42) ((38 as an ASQ Certified mechanical inspector, which just means I passed a test) I have as a mechanical inspector I’d guess it may still thread in ok (real definitive there, huh?) I’d think if it threads in it’s probably ok. But if it were my barrel I’d be raising holy hell with the manufacturer. That’s just unacceptable.
