The heavy-barrel version of the FNAR™ is also chambered in 7.62x51mm and features an ambidextrous magazine release and 20” cold hammer-forged MIL-SPEC fluted barrel with hard-chromed bore and target crown. A one-piece receiver-mounted MIL-STD 1913 optical rail comes standard, along with a trio of similar accessory rails attached to the adjustable synthetic stock’s fore-end for mounting a battery of tactical lights and lasers.
