Guntec Ultra Light Handguard Features The Guntec USA Ultra Light Handguard is machined from T6 aluminum and built around a proprietary barrel nut included with the handguard which lets the rail slide directly over the nut and index tightly against the upper receiver. Six screws secure that connection producing a rigid free floating rail that does not flex under sling tension or accessory mounting pressure. Because the handguard sits flush up against the receiver its top rail reads as one continuous monolithic 1913 Picatinny surface with the upper which simplifies co-witnessing optics and iron sights. The full M-LOK slot system along the sides and bottom gives shooters flexible placement options for lights grips bipods and other accessories. At 15 inches long this handguard gives builders substantial rail real estate for mounting a full accessory suite while keeping the barrel completely free floating for accuracy. The matte black finish matches standard AR-15 hardware and blends cleanly with most upper receiver finishes. Its ultralight construction keeps added weight to a minimum which matters on a build meant to stay fast-handling and front-light. Builders assembling a precision or general-purpose AR-15 upper will appreciate the combination of rigidity rail length and low weight this handguard delivers.
