What is the typical weight of the M240 machine gun?

The typical weight of the M240 machine gun is approximately 17 pounds, which makes option B the correct choice. This weight reflects the design and construction of the M240, a general-purpose machine gun widely used by the United States Marine Corps and other branches of the military. Its weight contributes to its stability and accuracy during sustained fire, making it effective in various combat scenarios.

The other options present weights that do not accurately match the specifications of the M240. The lighter weights like 10.5 pounds may suggest a smaller caliber weapon or a different model altogether, while weights significantly heavier than 17 pounds could indicate either a modified version or a misunderstanding of the standard M240's specifications. Overall, understanding the weight of the M240 is essential for military personnel, as it impacts its portability and effectiveness in the field.
