Difference Between Models

The M249 has been designated as two separate models, the Automatic Rifle (AR) and Light Machine Gun (LMG). The basic M249 is the same for both versions. However during handoff, the LMG version is fielded with additional equipment as identified below.

AR ROLE: STD LIN M09009 - The AR role is to replace selected M16 rifles. The magazine cartridge (NSN 1005-01-334-1507) 100 round assault pack is included for the M249 AR model.

LMG ROLE: STD LIN M39263 - The LMG role is to replace selected M60 machine guns. The M249 LMG is fielded with the following equipment for the machine gun role:

1. Adapter Assembly, Tripod (NSN 1005-01-225-1156).

2. Adapter, Ammunition Bracket (NSN 1005-01-425-6541). 1-8. CORROSION, PREVENTION AND CONTROL (CPC).

CPC of materiel is a continuing concern. It is important any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in the future.

While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials such as rubber or plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem.

If a corrosion problem is identified, it can be reported using SF 368, Product Quality Deficiency Report. Use of key words such as "corrosion", "rust", "deterioration", or "cracking" will assure that the information is identified as a CPC problem.

I The SF 368 should be submitted to: AMSTA-AR-QAW-C, TACOM-ARDEC, 1 Rock Island Arsenal, Rock Island, IL 61299-7300.

USMC users should submit SF 368 (QDR) in accordance with MCO 4855.10 to Commander, Marine Corps Logistics Base, Code 808, Albany, GA 31704-5000.

Air Force users submit Quality Deficiency Report (QDR) in accordance with TO 00-35D-54, TM, USAF, Materiel Deficiency Reporting and Investigating System, to WR-ALC/LZBS, Robins AFB, GA 31098-5330.

WARNING

Before starting the inspection DO NOT actuate the trigger until the weapon has been cleared. Inspect the chamber to be sure that it is empty. Check for obstructions in the barrel.

NOTE

Weapon must be inspected and/or gaged at least once annually for safety and serviceability. Guard and reserve weapons are to be gaged and inspected at least once every two years after initial gaging unless usage, deployment or other maintenance indicates a need for more frequent inspection/gaging after every training cycle. Regardless of weapon ownership, initial gaging/inspection will be one year after receipt of new or overhauled weapons. The appropriate interval starts at this time.

Condition code "A" weapons when received from a weapons manufacture or a DA overhaul program do not require gaging prior to first use. Scheduling of annual gaging should begin with the weapons receipt date.

US Marine Corps only requires to conduct acceptance limited technical inspection (LTI) to include gaging on all new or rebuilt weapons.
