Pmcs For M203a2 Grenade Launcher

All active Army M203/M203A1/M203A2 grenade launchers must be inspected and gaged at least I annually for safety. All Army Reserve and Army National Guard M203/M203A1/M203A2 grenade I 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 PMCS or other physical evidence indicates that an individual unit's M203/M203A1/M203A2 grenade launchers require inspections | 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.
