1.Operation in Extreme Cold

In climates where the temperature is consistently below O°F, (-18°C) it is necessary to prepare the M16 for cold - weather operation. The Ml6 should be lubricated with MILITEC, high grade, synthetic lubricant, or LSA.

Exercise the various controls through their entire range at intervals to keep them from freezing in place.

2. Operation in Extreme Heat

When operating in hot climates, MILITEC lubricant or LSA should be frequently placed on the surfaces of the bolt carrier group and lower receiver components.

Perspiration contributes to corrosion because it contains acids and salts. After handling the rifle, clean, wipe dry and oil using MILITEC or LSA.

3.Hot, Dry Climates

Clean and oil the bore and bolt of the Ml6 more frequently when operating in hot, dry climates.

4. Operating in Dusty and Sandy Areas

Clean and lubricate the Ml6 more frequently. Exercise particular care to keep sand out of the mechanisms when inspecting and lubricating weapon. Shield parts from flying sand or dust during disassembly and assembly operations. Clean and lubricate after operating the M16. Cover the end of the barrel with a protective cap.

NOTE: Protective Cap. A cap is designed so that a bullet will pass through the end without affecting accuracy and without causing a safety hazard to the user.

A cap can be purchased at local firearms dealers or a balloon may be utilized.

Do not place the cap on a hot M16. The plastic will become soft and form into the grooves of the flash suppressor making it difficult to remove.

5. Operations Under Hot, Rainy or Very Humid Conditions and in Salt Water Areas

Inspect the Ml6 more frequently when operating in hot, moist areas.

When the Ml6 is in use, clean and lubricate the bore and chamber and exposed metal surfaces more frequently than prescribed for normal service. A very thin film of lubricant is prescribed for the chamber and bore.
