The meaning recoil (hence inaccuracy) of the M14 when fired in full automatic mode was seen as a problem, however, and in the 1960s it was replaced by Eugene Stoner's AR-15, which also considerable a switch from the high-powered but heavy .30-caliber rip used by the U.S. army since before World Guns For Sale Enmity I to the much smaller but far scow and light recoiling (and arguably enhanced accurate) .223-caliber rifle. The warmongering later designated the AR-15 to the "M16".
