CAUTION Areas with hot, dry climates usually contain blowing sand and fine dust. Deserts can be hot during daylight hours and freezing during hours of darkness. This will severely tax the weapon as well as other types of equipment. The weapon’s continued operation will depend on strictly and routinely following detailed cleaning and lubricating procedures. CAUTION Do not dry clean the weapon. Do not use hot water or other solvents to clean the weapon. This will remove the teflon lubricant built up as a result of using CLP. CAUTION Apply only a light coat of CLP to the firing pin and firing pin hole in the bolt. CAUTION Do not mix lubricants on the same weapon. The weapon must be cleaned thoroughly during any change from one lubricant to another. Dry cleaning solvent (SD) is recommended for cleaning before changing lubricants. f TM 8370-50127-OR/21 CAUTION Ensure the swab goes completely through the compensator. Do not reverse the direction while the swab is in the bore or compensator. CAUTION When using the bore brush, do not reverse direction while the brush is in the bore.
