The statement 'The device installed on the dove tail mount during boresight verification is the M154' is true.

• A. True
• B. Not sure
• C. N/A
• D. False

Answer: (D)

Boresight verification uses a dedicated alignment device mounted on the dove-tail to align the sight with the weapon’s bore. The tool used is specific to the system and is typically a laser bore sight unit or another platform-approved bore sighting instrument. The statement that the device installed on the dove-tail mount during boresight verification is the M154 isn’t correct, because the M154 is not the bore sighting device used for this procedure. Always refer to the system’s manual for the exact bore sight tool required, as the alignment process relies on that tool to bring the optic’s line of sight into proper coincidence with the bore before making any sight adjustments.
