And you'd be right, I've no interest in ever watching the show. But I meant MacGyver as a stand-in adjective for improvised from whatever he found lying around. Funny enough, someone said it's probably real, so this IRL MacGyver dude here was killing it (and his neighbor too, quite literally).
Ok, then let me explain how off that is. MacGyver's famous for improvising things that work out of whatever's lying around. Not for creating realistic looking props that don't do anything. Another key aspect of the character is that he really hates guns.
