This sniper rifle company is trying to lighten the M240 medium machine gun

Let's face it, today's soldiers and Marines have a lot weighing on them.


Between gear, ammo, and weapons, some are carrying over 100 pounds. But how do you reduce that burden?

Barrett Firearms, which created the mighty M82A1 and M107 .50-caliber sniper rifles, has managed to do just that by improving the M240 medium machine gun. Now, the M240 is based on the FN MAG, which is is a classic machine gun used by many NATO allies.

This gun even replaced the M-60, which was the backbone of squad firepower for the U.S. military through Vietnam and Desert Storm.

The question comes: How do you improve a machine gun used by just about all of the Western world? The Army has developed the M240L, which uses titanium to lighten the gun, but they kept the riveted design, albeit with a 5-pound weight reduction.

However, Barrett managed make its 240LW medium machine gun five and half pounds lighter than the M240B without the use of exotic materials. The secret was in how they made the receiver. Barrett machined the receiver from forgings and welded them together, according to a brochure handed out at the National Defense Industry Association's 2017 Armament Systems Forum.

Not only did this reduce the number of components from 64 to two, it also helped take about five and half pounds off the machine gun. The change also has boosted the reliability of the gun – by removing the rivets – which can be shaken loose by firing thousands of rounds.

There's also less metal, due to the fact that there is no need to overlap the metal components.

Will the 240LW make an impact with the United States military? That remains to be seen, but it does show how Barrett manages to be very innovative when it comes to designing – or improving – small arms.

Check out these amazing uncovered photos of the great Ernie Pyle

On April 18th, 1945, war correspondent Ernie Pyle was killed by enemy fire on Iejima* during the Battle of Okinawa.

In remembrance of Ernie Pyle, the Unwritten Record presents photographs and motion pictures that highlight his work as a roving war correspondent during WWII.
