While Congress is busy arguing over how to pass a bump-stock ban, the Massachusetts legislature is already half way there.

Earlier this week, the state’s House of Representatives approved the joint petition by Democrat state Representatives David Linsky and Cynthia Stone Creem Linsky to ban the “sale of devices that increase the rate of discharge of certain firearms.”

Rep. Linsky believes bump stocks and other devices like them only have one purpose: “to kill or wound as many people as possible in a short period of time.”

According to the Mount-Vernon Registrar News, persons found in possession of one could face anywhere from three to 20 years in prison. However, it is unknown how the state will deal with Massachusetts residents who already own these devices.

Regardless, the proposal had nearly unanimous support. Only three out of 154 lawmakers voted against the legislation.
