I'm not missing the point. Those guns are cut in another country and shipped here. They don't have to cut them and sell them in the US if they wanted to preserve the "historical" value of a POS gun.
That other country does not have the 2nd amendment...so when you talk about the 2nd amendment, the country doing the cutting has to have one in order for it to be relevent.
The guns that are protected under the 2nd get more life by having parts availible.
