the standard u.s. military rifle ( m-16 ) is substantially more destructive than its russian counterpart ( ak-47 ) when fired at short range into clay blocks , despite the fact that the ak-47 is of larger caliber and fires a much heavier bullet with a kinetic energy ( muzzle ) 25 % greater when compared to the m-16 .
