What should be done after firing the M60E3 machine gun?

After firing the M60E3 machine gun, proper care and maintenance are essential to ensure its reliability and longevity. The correct course of action involves thoroughly cleaning the weapon for three consecutive days. This practice is crucial because it helps remove carbon buildup, dirt, and other residues that can impair the machine gun's functioning. Regular and thorough cleaning prevents jams, malfunctions, and potential degradation of components over time.

Cleaning is particularly important for machine guns due to their high rate of fire and the heat generated during operation. Neglecting proper cleaning can lead to operational failures in future use. The specified duration of three consecutive days emphasizes the need for diligence in maintaining the weapon in optimal condition.

While there are other steps that may need to follow after using the machine gun, such as storing it correctly or ensuring safety measures are observed, the priority should be thorough cleaning to maintain its operational readiness.
