This video features a social media experiment where three gun tubers (Ian McCollum of Forgotten Weapons, Karl Casarda of In Range TV, and Administrative Results) independently rank four iconic rifles for militia use: the FN FAL, HK G3, AR-15, and AK-47. The consensus among the experts is that the AK-47 is the superior choice for arming untrained conscripts due to its simplicity, reliability, and ease of maintenance, while the FN FAL and HK G3 are deemed too powerful and complex for such a role. The AR-15 is considered good for trained soldiers but less ideal for a ragtag militia.
