 * This gun is a reference to the Golden Gun from the James Bond movie The Man with the Golden Gun. The movie's villain, the assassin Francisco Scaramanga, uses the titular Golden Gun as his weapon of choice and boasts of only needing one shot per target.
 * "Some Assembly Required" refers to the fact that in the film, the Golden Gun is assembled from a series of golden innocuous looking items: a fountain pen (the barrel), a cigarette lighter (breech), cuff-link (trigger), and a cigarette case (the grip).
 * The flavor text is a reference to the James Bond game GoldenEye 007 for Nintendo 64 (and subsequent James Bond games) where it was unique in that it instantly killed anything it shot.
 * Au is the chemical symbol for gold.
 * The 22 ammo count is likely a reference to 22 karat gold known as "Crown Gold". The exception to this is the Pilot whose bonus increases the gun's ammo by 10% to 24, which would reference 24 karat or "Pure Gold". It may be tied to the flavor text.  "It doesn't live up to the legends, but it comes close" - The gun in the movie was 23 carat gold.
 * The synergy is a reference to the famous quote from The Thing, a superhero from the Fantastic Four group that belongs to the Marvel Universe.


 * The gun may also be a reference to Destiny’s Golden Gun super ability, which is an extremely powerful pistol.
