FN Improves Iconic MAG Machine Gun

I liked the M240 than the little buzz-gun M249.
-----------------------
In 1976, the Army officially adopted FN's MAG machine gun, labeling it the M240 and employing it exclusively as a coaxial gun on M1 Abrams tanks. The platform subsequently was adopted in various forms by every branch of the U.S. military. All are considered some of the most reliable martial arms ever designed, but the legendary firm doesn't have a habit of resting on its laurels. This year, it introduced a new variant, adding enhancements requested by those whose job requires time behind a trigger, often in hostile conditions.

BONUS

The U.S. Army has explored 6.8x51mm (6.8 × 51 mm) conversion kits for the M240B and M240L to achieve ammunition commonality with the newer M250 light machine gun.

Military testing and industry outreach for the M240 6.8mm conversion include:
  • Military Intent: The U.S. Army released formal requests for information and sources sought notices to convert existing 7.62x51mm M240 platforms to 6.8mm.
  • Kit Components: A conceptual conversion requires a new barrel assembly, along with potential modifications to the gas regulator and drive spring to handle the extreme chamber pressures of the 6.8mm round.
  • Industry Testing: Ammunition manufacturers like True Velocity have partnered with companies such as FN America (the OEM of the M240) to develop and test-fire these 6.8mm configurations on legacy belt-fed weapons.
  • Future Direction: While conversion kits are evaluated to bridge logistical gaps, the Department of Defense is also considering outright replacing some legacy M240s with dedicated 6.8mm platforms.
The 6.8x51mm round, developed by SIG Sauer as the .277 SIG Fury, operates at extreme pressures up to 80,000 psi (compared to 62,000 psi in standard 7.62mm NATO). Because of these high operating pressures and specialized hybrid-cased designs, civilian conversion or parts kits do not exist.
 
62k is the 308win chamber as the 7.62x51 nato is just over 60k...............if the writer doesn't know this, then maybe the writer shouldn't write about this then! if the nato round wasn't at that max pressure, then it would be safe to use 308win in nato chambers. unless nato or the us military changed something........................
