13.9" .223 Wylde Mid Fluted Polygonal Barrel

Features Polygonal SEPR Rifling technology which significantly reduces bullet deformation. Fired bullets have a symmetrical trajectory through the barrel and exist in the straightest line possible. The SEPR process also ensures the tightest seal of the projectile. This superb seal significantly reduces escaping gases and loss of gas pressures. Each barrel has undergone a precision honing and boring process, which produces a straight and glass-smooth rifle bore.
