Why You Should Abandon the AR-15
For the record, AR vs. AK arguments are gayer than a bag of dicks. Both go bang, and both throw a piece of copper-jacketed lead down range that you don't wish to get hit with. With all the other things to talk about in the "prepper blogsphere", yet another jackass has to keep beating that one dead horse.
It's as bad as the whole Baofeng HT thing.
It's way past time to shoot the whole argument with a .308, .30-06, or 8mm Mauser and move on.
