CARING AND CLEANING OF THE RIFLE
A clean, properly lubricated and maintained
rifle that is loaded with clean ammunition will fire
when needed. To keep the rifle in good condition,
you need to take care of it and clean it. Under bad
weather conditions, some key parts may need care and
cleaning several times a day. The cleaning material
(fig. 11-14) used for the care of the rifle is carried in
the rifle stock. Special attention must be given to the
barrel bore and chamber, bolt carrier group, upper
receiver group, lower receiver group, and the
Figure 11-14.M16Al and M16A2 rifle cleaning material.
Barrel bore and chamber
Dip a bore brush in the bore cleaner; then brush from the chamber to the muzzle, using
straight-through strokes. Dont reverse the brush while it is in the bore: it may jam. A
jammed brush is hard to remove, and removing the brush might damage the bore.
Dip the brush in bore cleaner; then clean the chamber with the bore brush.
Replace the bore brush with a slotted cleaning patch tip, and push the dry patches through
the bore and chamber until they come out clean.
After you clean the bore, lightly lubricate the bore and chamber to prevent corrosion and
pitting. Use the recommended lubricant on a patch.
Lightly lubricate the lugs in the barrel extension.
