Why Milsurp Rifles Shoot High

I just stumbled across this post on "The Firing Line". A new milsurp owner wondered why his Yugo M48 shot 14" high at 100 yards. Much to my amazement, nobody had a good answer for him. So in case you have ever wondered about this, here is the answer: conscripts in many places used to be trained to aim at the belt buckle of the enemy. This way, anyone who could fire a rifle could obtain a hit in the torso from point blank to 300 meters or 420 arshini. Individual soldiers did not normally raise the rear sight unless so instructed by their commander.
