BTW whats your point????? any unskilled person with a hack saw can also hack saw off the barrel on a shot gun and make a sawed off shot gun. Which is illegal to do and illegal to own. and its covered under the same law that outlawed machine guns in the 1930's without a tax transfer stamp each time the gun is transferred.
BTW in that case the supreme court ruled they could limit ones constitutional rights to arms when it came to sawed off shot guns because they could not reasonable see a sawed off shot gun having much military use or value to have to fend off tyrannical goverment forces. so its not covered by the 2nd Which is president that proves and confirms the 2nd amendment has nothing to do with hunting or personal self defense.
