Well it kind of cracks me up that I am even discussing this but I must admit the thought has crossed my mind. While I can see the value of a .22 LR for all of the reasons posted and it would definitely be my second choice in a rifle it will never be my first. If I can have only one rifle it is going to be my BCM build AR .223. .22LR might stop the dead with head shots but they also could ricochet around the skull and do nothing. Also .22 LR occasionally don't work (duds) and if they are out in the sun and get hot the wax can melt to the point that they jam a good bit in a semi auto. This all could ruin your day in a mad rush of WD. All of that is supposing that the WD is the only thing you will have to fight which as we have seen is not the case. Oh yes, I would like mine suppressed as well too.

Since most of the military would also be WD there should be a lot of 5.56 laying around.

As for knives I am torn. I probably will have to go with my 911 but I sure would like a sword.....
