That requires being well versed in... Math... specifically... Division... but being gun nuts we really get off on technical things like Division. The things gun nuts do is just socially horrifying. We're just evil. Not kim jung uuummmm evil, but just basically evil. Gun nuts pick their teeth in public. Gun nuts fart in airlocks. Gun nuts even laugh at most of the humor in the American Pie movie. How do you know if you're really a gun nut? Well, there's no sure way but there is a list of behaviors:

You might be a gun nut if:
...you and your new father-in-law go to a gun show...................... on your wedding day.
...you buy a gun at a shop only to find out you used to own it a couple of years ago.
...the largest gun store in your area calls you if they need something they can’t get elsewhere.
...you put a Hogue Grip on your car’s parking brake.
...your license plate reads: “DBL TAP”.
