I wouldn’t say “scared,” but she buys into the liberal “why would anyone NEED an AR15?” and “that’s not what the founders intended” points of view.
Truthfully, she doesn’t like that i have ANY firearms ...which is why the key to the gun cabinet is always on my person, and not an insignificant consideration in my preference for wooden stocks.
I move my rifles in padded range bags, but the 10-22 and Remington 341p are similar looking, except for barrel length. My wife wouldn’t care to notice that one is a bolt action, and the other accepts magazines. Likewise, she does not distinguish between blued pistols.
I can probably fill the cabinet with wooden stock rifles of varying calibers and not have her notice, but i restrain myself for the sake of marital harmony. Mostly.
