You realize many guns can be made full auto just by filling down or replacing a single part and the spring, right? It's been an issue for DECADES. This law was just reactionary legislation and didn't actually impact mass shootings. It being gone doesn't really change anything other than one less law to enforce.
Does America have a gun problem? Yes. Does it have an ass backwards bureaucracy problem? Also yes.
No they don’t (well… they do, but not for this). Bump stocks are a stupid gimmick that were only ever banned in the first place to appease low-information hysterical types.
