True Story: A Marine’s Sniper Rifle Failed During a Shootout—He Called Customer Service.

“It’s probably one of the biggest highlights of my life, to be able to help a Marine unit during a firefight,” Cook told National Geographic. 

The Barrett M107 .50-caliber long-range sniper rifle is a firearm made for the modern war on terrorism. Officially adopted by the U.S. Army in 2002 and boasting a 2,000-meter range, a suppressor-ready muzzle brake, and recoil-minimizing design, the semi-automatic offers “greater range and lethality against personnel and materiel targets than other sniper systems in the U.S. inventory,” in an assessment by Military.com .

While Barrett’s reputation of “flawless reliability” has made the M107 the sniper weapon of choice, the rifle is just like any other essential tool: It often breaks when you need it most. And that’s apparently what happened to one Marine Corps unit pinned down in a firefight, according to one of Barrett’s longtime armorers. 

Don Cook, a Marine veteran who’s been maintaining M107s for more than two decades, told National Geographic in 2011 that he one day received a call to Barrett’s workshop from a harried young Marine. During maintenance of the unit’s M107, the Marine had bent the ears of the rifle’s lower receiver; the next day, after engaging the enemy, they discovered the rifle wouldn’t fire consistently.
