DiFi pushes ban on semi autos
She announced the push via Twitter where she wrote: Americans across the nation are asking Congress to reinstate the federal ban on military-style assault weapons and high-capacity magazines. If were going to put a stop to mass shootings and protect our children, we need to get these weapons of war off our streets.
Feinstein wants to ban any assault weapon which accepts a detachable magazine and has one or more military characteristics including a pistol grip, a forward grip, a barrel shroud, a threaded barrel or a folding or telescoping stock.
