The speed of a bullet exiting the muzzle of an AR-15 semi-automatic rifle is 3200 feet per second. The gun is not as heavy as it looks. The civilian version of an M-16, the AR-15 has a long, black cylindrical body to which you press the soft side of your cheek. Squint into the glowing red sight, and a laser points the way to a bulls-eye.
