Guntec Air Lite Handguard Features The Guntec USA Air Lite Handguard is machined from 7075 T6 aluminum into a free floating design that slides over the included lightweight aluminum barrel nut and locks against the receiver with six screws. Free floating the barrel from the handguard keeps outside pressure off the barrel which helps maintain consistent accuracy shot after shot. Triangle and diamond cutouts run throughout the 15 inch body trimming weight from the handguard without compromising the structural integrity of the T6 aluminum construction. The monolithic 1913 Picatinny top rail runs the full length of the unit giving a continuous mounting surface for optics sights and other top-rail accessories. Three M-LOK slots are positioned on three sides of the front end letting shooters mount lights foregrips bipods and slings exactly where they need them without adapter rails. The matte black finish matches standard AR-15 furniture and resists wear from regular handling and field use. At 15 inches this handguard suits mid length and rifle length gas system builds looking for extended rail coverage. For builders and upgraders assembling a lightweight accessory-ready AR-15 the Guntec USA Air Lite Handguard is a straightforward well-equipped choice for sale at GrabAGun.
