That Gun for the Blade Runner reference

This Machine is also a reference:

This Machine is an unique battle rifle, a gas-operated, semi-automatic, clip-fed rifle chambered for the .308 round.

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.
