Sig Sauer M250A1 light machine gun variant shortened and lightened

Sig Sauer unveiled an M250A1 update to the US Army’s new 6.8x51mm M250, featuring a shorter 13-inch barrel option, weight-saving barrel tapering, and changes aimed at reliability and handling. The variant also revises the barrel-change arrangement (adding a quick-change barrel handle/heat insulation concept), indicating iterative design changes based on soldier feedback as NGSW is fielded.
