Upper Receiver

1. Place several drops of gun solvent on a .223 caliber brush and clean the barrel from the chamber to the muzzle.

NOTE: Never clean any rifle barrel from the muzzle to the rear. The rifling may be damaged causing the weapon to fire inaccurately.

2. Replace the bore brush with a chamber brush and clean the chamber and lugs with solvent.

3. Brush any carbon build-up on the flash suppressor with a tooth brush dipped in gun solvent.

4. Run numerous oiled and dry patches through the barrel until free of residue.

5. Place two drops of MILITEC or LSA on a clean patch and lightly coat the barrel.

6. Brush and wipe all remaining residue from the inside of the upper receiver and Charging Handle rail. (See photo.)

7. Wipe the Charging Handle free of residue and place two to three drops of MILITEC on the exterior.
