MARINE CORPS BASE QUANTICO, VA --
Recon Marines and scout snipers now have a new weapon in their arsenal.
The Mk13 Mod 7 Long Range Sniper Rifle is a bolt-action, precision-firing rifle that offers more accuracy and range than similar weapons of yesteryear. The system partially replaces the M40A6—the legacy system—and gives Marines increased lethality.
In the second quarter of fiscal year 2019, the Mk13 reached full operational capability.
Scout snipers are now being fielded a weapon system that makes them even more lethal at distance than they were previously Capt. Nick Berger, Marine Corps Systems Command’s project officer for the Mk13
“This weapon better prepares us to take the fight to any adversary in any clime and place."
The Mk13 delivers a larger bullet at greater distances than the legacy sniper rifle. The additional velocity offered by the Mk13 will be advantageous on the battlefield, said Berger.
“When shooting the Mk13, the bullet remains stable for much longer,” said Maj. Mike Brisker, MCSC’s weapons team lead for Infantry Weapons. “The weapon gives you enough extra initial velocity that it stays supersonic for a much longer distance than the M40A6.”
Additionally, the rifle includes the M571, an enhanced day optic that provides greater magnification range and an improved reticle. The new optic enables Marines to positively identify enemies at greater distances and creates a larger buffer between the warfighter and adversaries.
Mk13 a ‘positive step forward’
The M40A6 has served the warfighter well for many years. However, the Corps searched for ways to enhance their sniper capability after identifying a materiel capability gap in its sniper rifles, said Brisker. He said Marines will primarily use the Mk13 during deployments, while the M40A6 will serve as a training rifle for snipers.
“We are looking to conserve the barrel life of the Mk13 Mod 7 and facilitate training aboard all installations,” said Berger.
Since its initial fielding to I Marine Expeditionary Force in 2018, the Mk13 has been popular among Marines. The 3rd Battalion, 5th Marines Scout Sniper platoon used the weapon for more than a year in support of the 2025 Sea Dragon Exercise. Many users emphasize how the weapon significantly improves their precision firing capability, said Berger.
“At our new equipment trainings, the resounding feedback from the scout snipers was that this rifle is a positive step forward in the realm of precision-fire weapons,” said Berger. “Overall, there has been positive feedback from the fleet.”
Both Berger and Brisker expressed encouragement for the Mk13 after the weapon reached FOC. They believe the rifle will give the warfighter an additional option, increase lethality and enhance the ability to execute missions on the battlefield.
“The fact that we managed to get a gun of this capability out to our sniper teams is really positive,” said Brisker. “We’re looking forward to doing even more in the future.”
