My rifle is to fight my way back to my handgun.
No not really, but for me my "fighting" rifle (m4) is more for fun. Yes I have a red dot optic and BUIS, and yes I've taken 'tactical' rifle classes with it. But I really don't think as a civillian, I'll ever need to use it as a weapon to defend myself with, at least not while our society remains intact. Besides, the only time I even have my rilfe with me is when Im at home. If I needed a weapon to use for home defense it wouldn't be my rifle. I'd probably go with either my glock 22 or 12 gauge.
