WARNING

Clear the weapon before starting an inspection. Do not squeeze the trigger until the weapon has been cleared. Inspect the chamber to be sure that it is empty. Avoid having live ammunition where maintenance is performed.

Using the old style firing pin, Part Number 8448327, can cause injury to personnel and damage to equipment when firing a live round. The old firing pin must be replaced by the new firing pin, Part Number 12002970, whenever the old pin is identified in the weapon.

To avoid injury to your eyes, use care when removing and installing spring-loaded parts.

Dry cleaning solvent is FLAMMABLE and TOXIC and must be kept away from open flames and used in a well-ventilated area. Use of rubber gloves is necessary to protect the skin when washing grenade launcher parts.

Appropriate eye protection is recommended when cleaning your weapon and/or its parts.

I All Active Army M203/M203A1/M203A2 grenade launchers must be inspected and gaged at least once annually for safety. All Army Reserve and Army National Guard M203/M203A1/M203A2 grenade launchers must be inspected and gaged at least once every two years, after the initial inspection/gaging procedures have been accomplished. The initial gaging procedures for Active Army, Army Reserve, and Army National Guard are required one year from receipt of the weapons. This two-year interval may be maintained unless preventive

(maintenance checks and services (PMCS) or other physical evidence indicates that an individual unit's M203/M203A1/M203A2 grenade launchers require inspection at a more frequent interval. If it is determined that a yearly inspection is necessary for an individual unit, only that unit will be affected. This will not affect other units in regard to the interval of inspection.
