This video details the cause of a 'clocked barrel' in a PSA upper receiver, which is the barrel rotating within the upper receiver during barrel nut installation. The issue stems from improper fixtures not holding the upper and barrel securely, allowing the barrel index pin to peen over the receiver material. The instructor recommends using the correct tools, such as Midwest Industries rod, to prevent this common assembly error and ensure proper alignment.
