The Nemo XO Carbon, short for Executive Order, is a .308 Winchester precision carbine (Nemo part no. XO30820CF) built to be lightweight, accurate, and hard-hitting. It’s available only with a 20-inch Proof Research barrel, and the longer barrel ensures shooters extract maximum velocity from their projectiles. Ambidextrous controls make operating the XO straightforward for any shooter, and this example is finished in Tungsten Cerakote for a distinctive, durable look. Feeding from a 20-round magazine, the XO Carbon suits hunters and long-range shooters who want serious .308 performance from a semi-automatic AR platform.
