AR-15 vs. Blackpowder rifle? Which would you choose?
Which of these 2 rifles will allow you to survive the longest?
Which of the 2 rifles will continue working under the worst of conditions?
Which of the 2 rifles can your repair, supply, and maintain in extreme survivalist situations?
I personally would pick the Blackpowder rifle, I can always make my own powder (charcoal, sulfur, and potassium nitrate), cast my own bullets out of lead, is a more simple design, and has fewer moving sophisticated parts than the AR-15.
