What Is the Best Home Defense Ammo for AR-15 ?
This informational video from the U.S. Concealed Carry Association (USCCA) discusses the best ammunition for AR-15s used in home defense scenarios. Director of Content Kevin Michalowski explores various ammo types and weights, emphasizing the importance of choosing the right rounds to avoid over-penetration. He highlights that while AR-15s chambered in 5.56 NATO can fire .223 Remington, the reverse is not safe. The video touches on the effectiveness of standard 55-grain 5.56mm bullets at close range and the function of frangible ammunition designed to break apart on impact with solid surfaces, mitigating ricochet risks.
