Snipers are undoubtedly the most lethal shooters on the battlefield, able to take out targets from hundreds and hundreds of yards away, without their marks being alerted to their presence.

They are experts at blending into the environment, masters of patience, physically developed, and always well-trained. But snipers still can’t take the shots they’re known for without a decent rifle in their hands, capable of helping them reach targets at longer-than-normal ranges.

Over the past 50 years, records for the longest kill-shots in history have been made and broken repeatedly by some of the greatest snipers the world has ever seen. These are the four guns they have used to break and set these records on confirmed kills at unimaginably far distances:

A WWII-era machine gun used as a sniping system doesn’t exactly evoke any images of precision shooting, but it’s exactly what a 24-year-old Marine by the name of Carlos Hathcock used in early 1967 to take out a Vietcong militiaman pushing a bicycle loaded with weapons and ammunition. Built to fire the .50 BMG round, the M2 had exactly the range and stopping power Hathcock wanted in a gun that would allow him to hit targets at distances far beyond what a standard-issue sniper rifle permitted.

With an Unertl scope mounted to a custom-made bracket crafted by Hathcock himself and the M2 in single-shot mode, the gun could engage targets at distances over 1,600 yards. The machine gun was balanced on an M3 tripod and kept in place with sandbags.

His record-breaking February 1967 kill was made using this setup at 2500 yards, creating a record for the history books which would stand until the War in Afghanistan in 2002.

According to Chris Martin in his book, Modern American Snipers, Sgt. Brian Kremer currently holds the American record for the longest sniper kill in Iraq, while serving with the 75th Ranger Regiment. The M82 SASR is every bit the beast it looks, firing a .50 Browning Machine Gun round at effective ranges up to nearly 2,000 yards. Weighing in 30 pounds, and measuring 48-57 inches long depending on the barrel used, the M82 is without a doubt one of the most fearsome small arms on the battlefield.

The M82 was originally put into service with the U.S. military in 1990 and has been used in every conflict since. Though smaller-caliber sniper rifles are typically unable to hit targets behind cover, American snipers have been able to use the M82 and the Raufoss Mk 211 .50 caliber round to simply shoot their way through obstacles at great distances to reach their marks. Kremer’s shot reportedly measured 2,515 yards.
