The reason for this is that altered military rifles will rob 7-11 stores, but sporting rifles have better upbringing. You can't trust an altered military rifle. They do bad things.

A similar condition is true of the AR-15 family of rifles. It has been conclusively demonstrated that a bayonet lug will cause the rifle to attack people, especially if a flash suppressor is present to agitate the rifle. This is only true of rifles that were made after September 13, 1994. AR-15 rifles made before that date, or after September 13, 2004 do not have this personalty flaw. All AR-15 rifles that were built without the bayonet lug are good natured and cannot do harm to people.
