Its a valid question Gnu, the sportsmen would support a law to restrict this stuff, but it never gets to even a bill in congress. Out political leaders have no courage or are getting money for their campaign from the NRA. Don't know. Oh they will pass a stupid law like no more then 10 round clips but even that is nonsense since a billion grandfathered clips exist. Yet I can buy a 50 round drum magazine for an AK at a show legally. There are more than 20,000 gun laws and pretty much all of them are left at the door when entering a gun show. Bob is right in that regard, no gun laws at all there. So our leaders pass nonsense laws that only impact sportsmen or competitive shooters and let the bad guys run amuck with assault weapons without restrictions of any manner.
