Winchester recently issued an important product safety notice, recalling certain lots of Winchester 64gr Power-Point .223 Rem ammo. According to The Firearm Blog, “catastrophic failures destroyed a number of law enforcement AR15 type rifles.” That Blog cited LEO agency notices describing guns that suffered cracked uppers and bowed lowers after firing Winchester’s 64gr Power-Point .223 Rem ammo. Rifles built by three different manufacturers (Colt, Bushmaster, and Stag Arms), all sustained similar damage.
