What makes a gun semi-automatic? Key gun terms explained as House passes new legislation by Jessica Taylor Price - Contributor June 10, 2022 Share Mastodon Facebook LinkedIn Twitter The House passed the Protecting Our Kids Act on Wednesday, hours after hearing harrowing testimony from gun violence survivors and their families, and two weeks after a shooter killed 19 children and two teachers at Robb Elementary School in Uvalde, Texas. The House bill is wide reaching: It would raise the minimum age to buy some semi-automatic weapons to 21, strengthen bump stock and “ghost gun” regulations, ban high-capacity magazines, and give local governments power to start high-capacity magazine buyback programs, CNN reports. The changes are unlikely to make it past a Senate vote. The federal legislation follows a push for gun control at the state level. Last week, New York passed a bill raising the age to buy a semi-automatic rifle to 21 and expanding red flag laws, CNN also reports. Meanwhile, New Jersey Gov. Phil Murphy called for laws that make gun manufacturers vulnerable to civil lawsuits, and California lawmakers pushed for stricter gun control. What do these restrictions mean, and how effective would they be if passed? Here’s a primer on key gun terms, from Jack McDevitt, professor of the practice in criminology and criminal justice at Northeastern. What are the terms used in the bill to describe firearms? Automatic rifle vs. semi-automatic rifle.

While we may associate the term “semi-automatic” with rifles, which are long guns with grooves in the barrel that help improve accuracy, it can apply to any type of weapon, including handguns. Automatic Unlike a semi-automatic weapon, an automatic weapon—an example would be a machine gun—continues firing without the shooter having to pull the trigger again. “Once you pull the trigger, it will keep firing as long as the trigger is pulled down, until there are no more bullets,” McDevitt says. Automatic weapons are illegal in most states, he says. Bump stocks Bump stocks make a semi-automatic weapon mimic an automatic, making them a loophole in many states’ automatic weapon ban. The term made it to the mainstream media after the Las Vegas shooter used a gun with a bump stock to kill 58 people at a festival. Bump stocks are illegal in most states, McDevitt says. AR-15 rifle.

Assault weapons have “very large bullets that do a lot of damage,” and can be semi-automatic (like an AR-15) or automatic (like an AK-47). This is the type of weapon that was used in the recent hospital shooting in Tulsa. Magazines Magazines are spring-loaded bullet canisters used to load a variety of gun types. High-capacity magazines hold more than 10 rounds. Pistol.

In addition, he notes that there are two suicides for every homicide in the United States. Handguns include revolvers, where bullets are loaded into a revolving chamber, or semi-automatic pistols, which are magazine-loaded. Police often carry the latter. Ghost guns These 3-D printed guns, or “ghost guns,” as they are called in the House bill, can be printed in parts and assembled and don’t have serial numbers, so it can be difficult to trace ownership, McDevitt says. What are the components of a gun law? Red flag laws “Red flag” laws allow someone close to a gun owner to ask a court to take that person’s weapons if they believe they may pose a threat to themself or others. The concerned citizen can be a family member, local police, or even school personnel. A red flag law is active in Massachusetts, McDevitt says, though it’s not commonly used, in part due to lack of awareness. “We need to get the word out to convince people that they’re doing a favor for the person that they’re concerned about,” he says. Universal background checks Expanding background checks is one of the most effective ways to lessen gun violence, and “there’s wide public support,” McDevitt says. While he says there is a federal law that requires Americans to have a background check to buy a gun, “there are huge loopholes,” like when purchasing at a gun show or from another individual. “Universal” background checks would close those loopholes and make it so any federally prohibited person—someone convicted of a felony or domestic violence, or involuntarily committed to a mental hospital—cannot have access to a gun.

By instituting a waiting period between when the gun is purchased and when it can be picked up, “the hope would be that the person’s anger would have calmed down and they wouldn’t act impulsively.” Permit requirements provide another barrier to access. To obtain a “license to carry” permit in Massachusetts, residents must be 21 or over, and they must submit an application and take a gun safety course. Meanwhile, residents as young as 15 can obtain a permit to own a firearm, as long as they have a parent’s consent. How does legislation affect gun violence? The Giffords Law Center, which compiles information on gun laws and gun violence by state, found a correlation between stricter gun laws and lower incidents of gun-related deaths. Mississippi, which Giffords gives an F grade for gun control, has the highest rate of gun deaths per 100,000 in the country, while Hawaii and Massachusetts, which received A- grades, have the lowest. But this doesn’t address the problem of people crossing state lines to get guns. While Massachusetts has strict laws, New Hampshire does not. “What we need to do is to make this a national set of rules so that the rules apply to all states equally,” McDevitt says. He doesn’t have much hope for Congress’ current legislation, though, saying the chances of it passing are “none.” After Sandy Hook, he says, most of the country’s gun legislation actually made it easier to get guns, and this time will likely be no different. “I don’t think anything’s going to pass this time. I hope I’m wrong,” McDevitt says. “I don’t see them coming together to build consensus.” McDevitt’s dream bill includes a national law that makes it harder for people who are violent to get guns and offers mental health support for those individuals. It would also include a fund to support victims of gun violence. In the end, though, “there isn’t a magic silver bullet out there that will solve all of our problems, unfortunately,” he says.
