NEMO XO CARBON 308WIN 20 | .308 Win | 20″ Barrel | 20rd

The NEMO XO Carbon is a 20-inch, carbon-wrapped barrel AR platform configured for .308 / 7.62 NATO. It combines a Proof Research carbon barrel, ambidextrous controls, and a Geissele SD-E two-stage trigger in a Cerakote finish. The design emphasizes accuracy, weight savings, and modular controls for a range of field and precision roles. A good optic pairing under $1000 is the Vortex Viper PST Gen II 3-15×44 for extended-range sighting without exceeding the mid-range budget.

Applications: precision target shooting; medium-game hunting.
