If the M122A1 tripod legs are not extending or locking properly, what should you use for maintenance?

The use of solid film lubricant (SFL) is appropriate for maintaining the M122A1 tripod legs when they are not extending or locking properly. SFL provides a thin, durable coating that can reduce friction and enhance the movement of mechanical parts. This type of lubricant is particularly beneficial in military applications due to its resistance to extreme temperatures and environmental contaminants, which helps ensure reliable operation under various conditions.

SFL is designed to adhere to surfaces and create a low-friction environment, which allows the tripod legs to extend and lock efficiently. In contrast, oil lubricants can attract dirt and debris, potentially causing buildup that could impede movement. Graphite lubricants, while effective in some applications, can also create mess and are less effective in harsh environments. Cleansing solvent is intended for cleaning rather than lubrication and would not provide the necessary lubrication needed to address the issue of the tripod legs not functioning properly.

Therefore, solid film lubricant is the best choice for ensuring optimal performance and maintenance of the M122A1 tripod legs.
