WTF???
Look, I love a .22LR. But that thing is ridiculous.
As far as one gun. .22? Nope.
AR-15 in .223.
Really, probably 12 ga. pump. 6 shot, buckshot and slugs.
But in a shtf situation, I'm going with the AR.
Would you really want to be by yourself in the wilds of Alaska or the wilds of Detroit with a .22? I'm thinking not. But it's your call.
I assume you read comments
#124,
#133 and
#135.
While I'm very familiar with the M-16 and know the difference in ballistics of the NATO 5.56 and the lesser powered .223; the M-16, AR-15 is designed to wound and not to kill.
I do NOT like it, but for weight and firepower for small-to-medium game, it's hard to beat; but as a man killer, I'll pass.
