US Army to field lighter M8 NGSW rifle replacing M7

The US Army will begin fielding the Sig Sauer M8 Next Generation Squad Weapon rifle in December, replacing the recently introduced M7 with a lighter, shorter configuration and feedback-driven design changes. The M8 keeps the 6.8×51mm high-pressure hybrid cartridge ecosystem while addressing soldier complaints about weight, length, and component wear. The article also notes potential rapid conversion kits to turn existing M7s into M8s, enabling fast fleet-wide transition.
