"Six of the 10 deadliest mass shootings in the U.S. over the past decade have used an AR-15-style semi-automatic rifle. The latest instance was Wednesday’s high school shooting in Parkland, Florida, which left 17 dead and 14 others injured. The gun used in the shooting was a Smith and Wesson M&P AR-15, federal law enforcement officials told the Associated Press. The same model weapon was used in previous mass shootings, including the Aurora, Colo., movie theater shooting that claimed 12 lives and the rampage in San Bernardino, Calif., that claimed 14. These rifles and other versions of the AR-15 are the civilian equivalent of fully-automatic M16 rifles used by the U.S. military since the Vietnam War. They are fancied by gun owners because they are typically easy to purchase — often for less than $1,000 — and can be customized with a number of accessories, such as bump stocks, which essentially convert the semi-automatic weapons into fully-automatics. A bump stock was deployed by the assailant in the 2017 Las Vegas shooting, which left 58 dead, making it the deadliest mass shooting in modern American history. Up until that point, the country’s deadliest mass shooting had occurred just a year prior at the Pulse nightclub in Orlando, where the perpetrator used an SIG MCX semi-automatic rifle — highly similar to AR-15s in aesthetic and purpose — to kill 49 people. Comparable weapons were also used at Sandy Hook Elementary School (27 dead) and a Sutherland Springs, Texas, church (25 dead). The high number of fatalities in these incidents highlight how AR-15-style guns, much like their M16 cousin, are capable of inflicting serious damage to a number of people at once. “For practical purposes, for the person that’s just tuning in, the non-gun owner, it’s a very similar type of firearm,” Rob Pincus, who has made a career out of training armed professionals, told TIME."
"The gunman charged with killing 17 people at a Florida high school on Wednesday used an AR-15 model rifle, a style of gun that has become more commonly used in mass shootings in the past decade. The AR-15 is a semiautomatic rifle that allows the user to fire rapidly and use high-capacity magazines. Four out of the five deadliest mass shooting in modern U.S. history have taken place since 2012 and all four of those shooters used AR-15 model rifles in their attacks, including Stephen Paddock in Las Vegas and Adam Lanza in Newtown, Conn. The AR-15 model rifle is among the most popular firearms today, according to the National Shooting Sports Foundation, the firearms industry trade association. Gun owners like them because they are easily customized and can be used for hunting or target practice, according to the association. Some Democratic lawmakers and gun-control groups want to ban or restrict AR-15 model guns, calling them weapons of war."
"An AR-15 once again made an appearance at a mass shooting, this time at a Parkland, Fla., high school on Wednesday...These AR-style rifles have appeared in some of the deadliest shootings in the last few years, including a concert in Las Vegas, a nightclub in Orlando, a church in Texas and an elementary school in Newtown, Conn."
"On average, more than 13,000 people are killed each year in the United States by guns, and most of those incidents involve handguns while a tiny fraction involve an AR-style firearm. Still, the AR plays an oversized role in many of the most high-profile shootings, including the nightclub shooting in Orlando and the deadliest mass shooting in modern U.S. history: the attack by a gunman holed up in a Las Vegas hotel that left 58 dead and hundreds injured."
"AR-15-style rifles have been used in recent mass shootings at in Aurora, Colo.; Santa Monica and San Bernardino, Calif.; Orlando, Florida and now Parkland."
"Compared with pistols, assault rifles are used rarely in shootings. According to F.B.I. statistics, 374 people were murdered with any kind of rifle in 2016; 7,105 were killed by a handgun. But the AR-15 has been a recurring character in some of America’s most infamous violent crimes. Adam Lanza used his to kill 20 children and six educators at Sandy Hook. Stephen Paddock used an enhanced AR-style gun to kill 58 concertgoers and wound hundreds on the Las Vegas Strip in October. A month later, Devin Kelley murdered 26 congregants with a Ruger AR-15 variant at a church in Sutherland Springs, Tex. And the rampage last month at Marjory Stoneman Douglas High School in Parkland, Fla., renewed calls for assault-style rifles to be banned — a common refrain after mass shootings."
"Manliness means violent domination, a point not lost on gun manufacturers. Bushmaster, the maker of the AR-15 rifle — which has been at the center of many mass shootings — advertised the gun with a “Consider Your Man Card Reissued” tagline."
"In recent years, the AR-15 has become, simultaneously, one of most beloved and most vilified rifles in the country. It is no surprise why the gun is so reviled by gun control advocates. Omar Mateen, the gunman in the attack this weekend on a gay nightclub in Orlando, Fla., used a spinoff of the rifle produced by SIG Sauer to kill nearly 50 people. The military-style weapon has also been the gun of choice in several other mass shootings: at an elementary school in Newtown, Conn.; at a movie theater in Aurora, Colo.; at a holiday party for county health workers in San Bernardino, Calif.; and at the campus of Umpqua Community College in Oregon."
"His killing machine of choice was a mass murderer's best friend — and his enabler a gun lobby that has long opposed efforts to keep assault weapons out of the hands of blood-thirsty maniacs. The madman who killed at least 50 people and wounded 53 others at an Orlando club early Sunday was armed with an AR-15-type rifle."
"America has grown accustomed to military-style semi-automatic weapons such as the AR-15. It's not hard to see why: These firearms have been heavily marketed to gun owners. But at the same time, they're often the weapons of choice for mass murderers."
"It was used to slaughter first graders at Sandy Hook, murder Batman fans at Colorado movie theater, kill county workers at a holiday party in San Bernardino. Now a descendant of the AR-15 semi-automatic rifle — a Sig Sauer MCX — has the dubious distinction of being the weapon of choice for a homosexual-hating gunman named Omar Mateen who is being blamed for the worst single-day mass shooting in U.S. history."
"The AR-15 is America’s most popular rifle. It has also been the weapon of choice in mass shootings from Sandy Hook to Aurora to San Bernardino."
"The AR-15, the type of rifle used in the deadliest mass shooting in U.S. history, is the weapon of choice for mass killers...Unfortunately, the compact, easy-to-use lethality of the AR-15 has made it the weapon of choice in mass shootings."
"They're lightweight, relatively cheap and extremely lethal, inspired by Nazi infantrymen on the Eastern Front during World War II. They're so user-friendly some retailers recommend them for children, yet their design is so aggressive one marketer compared them to carrying a "man card"—although ladies who dare can get theirs in pink. And if the last few mass shootings are any indication, guns modeled after the AR-15 assault rifle—arguably the most popular, most enduring and most profitable firearm in the U.S. -- have become the weapon of choice for unstable, homicidal men who want to kill a lot of people very, very quickly."
"AR-15 style rifles have been the weapon of choice in many recent mass shootings, including the Texas church shooting Sunday, the Las Vegas concert last month, the Orlando nightclub last year and Sandy Hook Elementary School in 2012."
"The N.R.A. calls the AR-15 the most popular rifle in America. The carnage in Florida on Wednesday that left at least 17 dead seemed to confirm that the rifle and its variants have also become the weapons of choice for mass killers."
"While AR-15 style rifles have become the weapon of choice for some of America’s most recent and deadly mass shootings, these military-style guns are still comparatively rarely used in everyday gun violence. Between 2010 and 2014, only 3.55% of gun murders were carried out with any kind of rifle, according to a Guardian analysis of FBI data. The majority of gun murders are still committed with handguns."
"AR-15-style rifles have become something of a weapon of choice for mass shooters. One was used last year to kill 26 people during Sunday morning church services in Sutherland Springs, Texas, and it was among the stockpile of firearms used a month earlier to kill 58 concertgoers in Las Vegas. AR-15-style rifles were also used at the shootings at Pulse nightclub in Orlando, Florida; at an employee training in San Bernardino, California, and at Sandy Hook Elementary School in Newtown, Connecticut."
"It adds insult to the literal injuries and loss of life suffered by today's victims that even though the killer was known to be too dangerous to have guns, his father chose to rearm him including, reportedly, with the AR-15 used this morning, a weapon of war that now happens to be the weapon of choice in far too many mass killings in America."
"The mass murder last week at the Pittsburgh Synagogue has something in common with the deadliest massacres: the AR-15 semi-automatic rifle. Variations of the AR-15 were used to kill at a Texas church, a Las Vegas concert, Marjorie Stoneman Douglas High School in Florida and Sandy Hook Elementary School. The AR-15 style rifle is the most popular rifle in America. There are well over 11 million, and they are rarely used in crime. Handguns kill far more people, but the AR-15 is the choice of our worst mass murderers. AR-15 ammunition travels up to three times the speed of sound."
"They are Barbies for boys."
"Smith & Wesson is one of many firearms manufacturers to produce a version of the AR-15, marketing more than a dozen models that range in price from about $700 to $2,000. The weapon is popular among collectors, military veterans and target shooters who say it is easy to handle and can be modified in numerous ways. Some soldiers call it “a Barbie doll for men” because it has a wide range of accessories and replacement parts, including different styles of barrels, stocks, magazines and scopes."
"Enthusiasts praise the AR-15 rifle as lightweight, durable, accurate and, compared with other long guns, gentle in its kick. They describe the rifle as a gadget geek's dream—the "Barbie doll" of firearms, as one gun dealer described it—because of an array of accessories that allow it to be easily customized."
"This is the man's Barbie doll — you know, the Mr. Potato Head of firearms, because you can interchange so many different things to make it customized to you, to be able to make it comfortable when you shoot."
"For the most part all those add-ons are primarily cosmetic (folding stocks, bayonet mounts, pistol grips, etc.), which is why some AR-15 enthusiasts like to call them Barbie Dolls for Men."
"Enthusiasts sometimes describe the AR-15 as “the man’s Barbie doll,” an almost infinitely malleable collectible that owners can accessorize with infrared scopes, grips, flashlights and other add-ons."
"This morning’s massacre of innocent civilians in Orlando is more horrific evidence of the unique lethality of the AR-15. It is no wonder that this weapon was chosen by today’s shooter, as it has been by so many before him, and as it undoubtedly will be again. It was designed for the United States military to do to enemies of war exactly what it did this morning: kill mass numbers of people with maximum efficiency and ease. It is the gold standard for killing the enemy in battle, just as it has become the gold standard for mass murder of innocent civilians. The gun industry pretends the civilian AR-15 is vastly different than the military version, because it does not have select fire. This is a charade: the industry knows that the weapon is most lethal in semi-automatic “one-shot, one-kill” mode, yet these companies continue to sell it to civilians, abandoning reason in exchange for profit."
"I turned 18 the day after. Woke up to the news that my best friend was gone. And I don’t understand why I can still go in a store and buy a weapon of war. An AR. I was reading today that a person, 20 years old, walked into a store and bought an AR-15 in five minutes with an expired ID. How is it that easy to buy that type of weapon? How is it that easy to buy this type of weapon? How do we not stop this after Columbine? After Sandy Hook? I’m sitting with a mother who lost her son. It’s still happening...We need to do something. That’s why we’re here. So let’s be strong for the fallen who don’t have a voice to speak anymore. And let’s never let this happen again. Please. Please."
"This is an instrument of war designed for the battlefield that is marketed and sold to the general public."
"The specifications of assault-style rifles vary depending on ammunition, but many tests put the muzzle velocity of a standard round from an AR-15 at 3,200 feet per second, making it accurate up to 500 yards ― more than a quarter-mile. This makes rounds from an AR-15 or other assault-style weapons far more devastating than those fired from small-caliber handguns."
