I believe the civilian equivalent of a patrol rifle should be a little different, especially in rural areas.
It should:
o look fairly harmless;
o be quick to shoulder and fire;
o fire a catridge capable of rapidly disabling a vehicle or killing a large animal.
I like AR15s*, and they have become our modern battle rifle. For my vehicle gun, I prefer my 7600 .35 Whelen, with peep sight and stock shortened to my LOP. God forbid I ever have to use it in an emergency, but even our media probably won't call it a "pump action assault weapon", and it can kill anything on the continent. Because it takes detachable mags, you can even have two different loads ready, one a heavy penetrator, and the other lighter, faster, and rapidly expanding.
*Wow. Did I just say that?
