Fortis Manufacturing Camber Handguard Features The Fortis Manufacturing Camber Handguard uses the new Camber Lock mounting system engineered as the next evolution of Fortis s already popular handguard lineup for end users who demand a more rock-solid platform. A stainless steel barrel nut paired with locking camber nuts delivers rigidity alongside genuine weight savings built specifically for strength without unnecessary bulk. Installation only requires a high quality castle nut wrench along with the included T30 Torx L-key letting the rail lock down in a matter of minutes. This same simplicity makes the handguard easy to remove later for service without the hassle some competing systems introduce. Machined from aircraft grade 6061-T6 aluminum and finished in Type III hardcoat anodized Black the handguard offers a narrow 1.34 internal diameter for a slim comfortable grip. A continuous top rail spans the entire 15.3 length for uninterrupted optic or sight mounting while M-LOK slots sit at the usual 3 6 and 9 o clock positions with additional slots at 1:30 4:30 7:30 and 10:30 for lights and switches. At 9.98 oz for the handguard and 2.9 oz for the barrel nut the system keeps overall weight reasonable for a rail of this length. Made in the USA the Fortis Camber Handguard delivers genuine rigidity and easy maintenance for serious AR-15 builds.
