Woooh...
This would be kinda tough, as I feel if someone saw you hauling around some nice rifles on your backpack, he would not hesitate to take them for himself.
Sooo...
I would take ONE 14.5 inch M4 with a flat top & BUIS + micro ACOG.
A collapsable stock is also mandatory.
If their is room a Ceiner 22LR kit with 2 magazines.
Supressor
It would be carried broken down and hidden in a backpack.
I would also take a concealed 9mm, preferably a XD40 or similar reliable 9mm pistol.
Any quality made replica flintlock pistol, preferably as modern as a flintlock pistol can be in .45 caliber + a bullet mold.
This way, when we are all out of centerfire ammunition I can make natural blackpowder and use lead wheel weights off of cars to keep shooting.
One Cricket .22LR or similar *SMALL* bolt action 22LR rifle with threads to accept the M4's supressor.
This would be the gun I would tote around unconcealed. (supressor OFF unless I am DEEP in the woods) If someone was to ambush me, I would be in some ????... but then again I wouldnt want to attract attention with a nice centerfire semi auto in the first place. It would only come out of my backpack when I am ambushing or have the need to assemble it.
Since three guns I am taking are very small, I would also reward my foresight with a nice cleaning kit and several bottles of oil.
I have everything covered.
Big game? Shoot it in the face with the AR15
Medium game? Shoot it in the neck with the AR15
Small game? Ceiner 22LR or Bolt action, shoot it in the face
Being Ambushed? XD-9, 2 in the chest one in the head
Ambushing people? Supressed AR15 in the chest
Ambushing a person sleeping/ drunk? Ceiner 22LR at 10 ft with supressor.
If im feeling nostalgic I could whip out the black powder pistol and shoot stuff in the face. Im pretty sure it would die too.
