To me, the Windham is way scarier than the Bushmaster, because, well...ummm...I'll let the name speak for itself.
But in all reality, law abiding citizens should never own weapons like these. Notice I said WEAPONS. They are not firearms.
These should be illegal for citizens to own, like yellow cake, RPGs, downloaded Rosie O'Donnell movies, and unpasteurized milk. Benign reasons for ownership, like going to the shooting range, be damned.
