Witness Mark and Barrel Questions

Gentlemen,
Torque of straight threads arrested by two parallel surfaces using precision tools with which to apply the measured torque will results in varying degrees of alignment of witness marks. This is not conjecture, but fact. The initial application of torque will fatigue and stretch the metal. The second time that measured torque is applied to the barrel and receiver, the results will be misalignment.
Additionally, original factory witness marks will have the bottom of the mark occupying a common plane on both receiver and barrel.
