Last I knew Randy Weaver was targeted because he wouldn’t become a snitch for the govt currently under Eric Pimpton Holder. Nothing to do with Weaver’s tactical hacksaw. He told them he could cut off barrels all day long if they wanted him to do it.
I think there are AR type shotgun stocks. Whats the point of a length requirement when you can buy a pistol handle self defense shotgun over the counter now?
