Not being snarky, but in what setting will you use your battle rifle (I have one, too)?
I live downtown in a high rise but have a friend who owns a well concealed farm. He would welcome extra marksmen.
My worry is rioters invading our building through the main lobby. At that range a handgun would do just as well.
It is no longer in doubt that we will have to shoot to defend ourselves & loved ones.
If I’m in my car surrounded by a hostile mob bent on mayhem, I will floor it and deal with the aftermath. It’s a 2,500 lb minivan so will be used to good effect.
