What is the purpose of a field expedient boresight with the RPG-7?

The primary purpose of a field expedient boresight with the RPG-7 is to create a crosshair alignment with a target. This process involves aligning the weapon’s sights with the barrel's axis to ensure that the trajectory of the fired round corresponds accurately with the point of aim. Proper alignment is crucial for effective targeting, particularly in combat situations where immediate and accurate engagement of targets is necessary.

By achieving this crosshair alignment, operators can enhance their effectiveness in hitting designated targets, which is vital for mission success. Effective boresighting ensures that the operator can engage threats confidently and maximize the weapon's accuracy at various ranges.

In contrast, preparing for long-range shooting involves considerations such as ballistic adjustments and environmental factors that go beyond simple sight alignment. Adjusting the firing pin focuses on mechanical aspects of the weapon rather than the sighting system. Checking for weapon cleanliness pertains to the maintenance and operational readiness of the weapon, rather than directly influencing targeting accuracy.
