It further states that the armorer should inspect the barrel pin and receiver slot alignment for signs of wear, by bore sighting a vertical line and referencing the front sight. This suggests that clamping the barrel and torquing the barrel nut might cause the slot to widen or the pin to bend, causing a potential misalignment. Such a misalignment can potentially cause problems with the bolt locking properly.
