I am guessing when the factory tapped the adjustable sight attachment screw hole in the barrel, they did not get all of the swarf out and pushed a bulge into the rifling with the bottoming tap. The small bulge sits right in a groove. Is there a way to smooth that spot out without risking damage to the otherwise really nice bore? PS, Size wise it is like you placed a bit under half of a BB in the groove.
