Yes. We should. No one has given me a single reason that we should not. Also, we cannot is not an argument. Contrary to what big dog off the chain says, I've read the Constitution. Congress can regulate things having a substantial affect on interstate commerce for the general welfare. Or tax the shite out of ammo. Assuming Congress can prove a substantial relationship to commerce, which they can, boom. Also, States themselves have every right to enact legislation to ban automatic weapons. And I never said "assault rifles."
