You know your a gun nut when your wife tells you you have to many guns. And you can come up with a reason why you need another one. Besides saying but I won't it.
I do this all the time. "Why do you need another AR you have one." Because this one is a 20" the other is 16". I can shoot farther with better accuracy. "We'll why do you need the 16"? Because the 20" is to long for cqb.
