AOW's are $5 transfer or $200 tax to manufacture without a SOT, SBR's and SBS's are $200 transfer or production tax. Also Canada which is extremely repressive doesn't regulate shotgun barrel length at all and the children are ok, just points for other people to put in their letters.
Or maybe point to the man from spokane (http://seattletimes.nwsource.com/htm...apons21m0.html) who was just arrested with 37 machine guns, 9 silencers, 54 HE 40mm grenades, and six blocks of C4 that had no registration, or the bank robbers with illegal full auto AK's a couple years ago by the soldiers/ex soldiers so the laws are already not working and people are getting the weapons anyways. If criminals are driving down the street at 90mph lowering the speed limit from 25 to 20 will not fix the problem. More restrictive gun laws wont fix the problem failing to prosecute current ones creates. Law abiding citizens are asking to lawfully own weapons the criminals already have or are making, why hamper a citizen from trying to follow federal laws?
