This is true, and a good comment. It sort of supports what I am saying though; there actually aren't a lot of gun owners who think it is tyrannical to have regulation around this. And besides, the percentage of crimes committed in the US with an AR-15 (let alone an AR-15 modified in that way) is so low that the actual problem could almost be classified as non-existent, so it is not a surprise that there is not an uproar about it. Your point is taken however, thank you for the info.
