What is required for proper sight alignment with the M240?

Proper sight alignment with the M240 involves using both a front sight post and a rear sight, which are crucial for effectively aiming the machine gun. The front sight post provides a point of reference that ensures the shooter can accurately line up their aim with the target, while the rear sight offers support to achieve a consistent alignment by allowing the shooter to focus on both sights.

Using only one sight lacks the necessary support for precision shooting. The inclusion of advanced aiming devices like a laser sight or targeting computer might enhance targeting capabilities, but the foundational requirement for accurate aiming with the M240 remains the alignment of both the front and rear sights. This traditional sighting system is effective for ensuring accuracy and consistency in various shooting conditions.
