The End of 5.56 NATO! New Cartridge is 5X Better!
The US military is transitioning to the 6.8x51mm (.277 Fury) cartridge as part of the Next Generation Squad Weapon (NGSW) program, replacing the 5.56x45mm NATO. This new caliber offers significantly increased lethality and effective range, driven by its ability to handle higher pressures (up to 80,000 PSI) and deliver superior energy. The system includes the Sig Sauer XM7 rifle and XM250 light machine gun, paired with advanced fire control systems like the XM157.
