Fortis Manufacturing Camber Handguard Features The Fortis Manufacturing Camber Handguard is built around the company s patent pending Camber Lock mounting system one of the most solid mounting solutions available in the AR-15 handguard market. A stainless steel barrel nut compatible with a standard castle nut wrench works alongside locking camber nuts purpose built for both rigidity and weight savings. Installation requires only the castle nut wrench and the included T30 Torx L-Key letting the rail lock down in a matter of minutes. This same simplicity makes the handguard just as easy to remove when the weapon needs service. A continuous top rail runs the full 11.8 inch length for mounting optics back-up sights or other rail-mounted accessories. M-LOK slots at the standard 3 6 and 9 o clock positions are joined by additional slots at the 1:30 4:30 7:30 and 10:30 positions giving shooters far more placement options for lights and switches than a standard three-slot layout. Machined from aircraft grade 6061-T6 aluminum and finished in Type III hard coat anodizing the handguard resists wear while keeping weight down at just 8.36 ounces. Made in the USA the Fortis Camber Handguard is a serious upgrade for any AR-15 builder for sale at GrabAGun.
