The TRW Low Maintenance Rifle or LMR was a proposed insurgency weapon designed by TRW Inc. (formerly Thompson Ramo Wooldridge) of the United States during the Vietnam War. The intent was to produce an easy-to-use and operate firearm which could be disseminated to insurgent forces supporting the United States' military interests. The design utilized the same 5.56×45mm NATO ammunition and STANAG magazines as the M16 rifle. It would have been equipped with the M6 bayonet along with its M8A1 scabbard.
Development began in 1971, and ceased in 1973 with the weapon never having been fielded.
