Lubrication
Apply a generous coat of lubricating oil to the carrier bolt, external
surface of the bolt assembly, and interiors of the upper and lower
receivers, including all operational components.
Note: Ensure oil is not placed on the locking lugs of the bolt.
A light coat of oil should be applied to the barrel chamber and bore,
the firing pin, the firing pin recess in the bolt, and all external metal
surfaces of the rifle.
Place one drop of oil in the bolt carrier key and ensure that hidden
screws and springs are not overlooked.
Place a light coat of lubricating oil on the magazine spring. Do not
lubricate other parts of the magazine.
Note: Use semi-fluid lubricating oil (LSA) for temperature ranges
of -35F and above and weapons oil lubricating (LAW) for
temperature ranges below zero degrees. Either lubricant can be
used at temperatures ranging from zero to -35F.
Cartridges with light corrosion, mud, dust, dirty water, and/or rain
should be wiped clean with a dry cloth.
Note: Do not attempt to fire damaged or badly corroded
ammunition. Do not use oil or grease on cartridges.
