MAINTAINENCE
9.0. Maintenance
All firearms require periodic maintenance and inspection which
may reveal a need for adjustment or repair. Have your firearm
checked by a competent gunsmith annually even if it seems to be
working well, since breakage, improper functioning or corrosion
of some components may not be apparent from external examina-
tion. If you notice any mechanical malfunction, DO NOT
continue to use the firearm. UNLOAD the firearm and take it
to a competent gunsmith immediately for a thorough
examination. Similarly, if water, sand, or other foreign matter
enters the internal mechanism, immediately dismantle the firearm
for a complete and thorough cleaning. Failure to keep your
firearm clean and in proper working order can lead to a
potentially dangerous condition and an accident causing
serious bodily injury or property damage may result.
9.1. Cleaning
The SIG 556 rifle must be cleaned after each shooting session or
whenever performance is suspect. Clean the rifle as follows:
1. Unload the weapon per Section 5.0;
2. Field strip the weapon per Section 7.0;
3. Clean the barrel and chamber from the rear;
4. Clean other parts of the rifle, using care to remove carbon and
firing residue. Pay particular attention to the operating rod, gas
valve, and chamber areas;
5. Lightly lubricate areas of metal contact with a high quality
firearms lubricant or grease, paying particular attention to the
bolt/bolt carrier, receiver rails, operating rod, and gas valve;
