LOUISVILLE, Ky. (WDRB) — A bill to ban machine gun conversion devices, also known as switches, advanced in Frankfort Tuesday.

House Bill 299, sponsored by Rep. Jason Nemes, R-Louisville, would make possession of a machine gun conversion device a felony under state law.

The switch attachments are commonly called "Glock switches," but Glock does not manufacture the switches and has no involvement with the production of the devices.

They easily transform semi-automatic handguns into machine guns.

With the attachments, regular handguns can fire as many as 17 rounds in 1.03 seconds. The devices can let off 30 rounds in 1.8 seconds.

Federal law makes the possession or ownership of any machine gun manufactured after May 19, 1986, illegal and a federal felony.

Kentucky is one of two states that doesn't have state laws that restrict machine gun conversion devices.

HB 299 will mirror federal law to make it a felony to possess one of the devices in Kentucky.

The bill now moves to the House for a vote.
