Modular handguard/rail system gives the tactical shooter maximum flexibility to customize the number, position, and length of accessory rails on his rifle. Mount rails or sling swivels at 45° intervals around the handguard. Free-float handguard eliminates barrel pressure points for maximum accuracy; use a bipod or sling without affecting point of impact. Ventilated tube provides maximum heat dissipation, and the textured surface assures a non-slip grip in any weather conditions. Dual barrel nut system provides precise alignment of tube with top of receiver. Inner nut can be secured with a standard armorer’s wrench. Fluted aluminum outer nut reduces weight without compromising strength and is secured to handguard with flush-fitting, Allen head screws for rock-solid alignment with upper receiver. Handguard comes with two sling swivels; rails sold separately. Rail Kits designed for JP system, will also work with many other free-float tubes.
