This Machine is a unique battle rifle chambered in .308 caliber round, holding up to eight rounds at a time and is received in excellent condition thanks to Contreras's personal access parts. Along the rifle's left side are the words "WELL THIS MACHINE KILLS COMMIES", giving reference that this gun was used by American soldiers during the Resource Wars. This rifle is effective in mid-to-long range combat. However, long range combat is difficult because of the gun's relatively wide spread.
Although based off the M1 Garand, This Machine is not an exact reproduction.
This Machine has the exact same weight as the official weight—in pounds—of the M1 Garand
This Machine is a reference to Woodie Guthrie's guitar, which had a sticker stating "This Machine Kills Fascists" emblazoned on it. This Machine has the statement "Well This Machine Kills Commies" seemingly phrased as a direct reply, carved into its side.
In the game's files, as well as the G.E.C.K, This Machine is referred to as "WeapNVBattleRifleUnique", hinting that it was originally supposed to be the unique variant of a cut "battle rifle". The battle rifle later appears in Gun Runners' Arsenal as the common variant, albeit exclusively available from merchants.
