The Q LLC Q-Sert AR Handguard is a premium 9 free-float rail system engineered for the AR-15 platform. Precision-machined from high-strength 6061-T6 aluminum, it features a durable black finish and integrated stainless steel inserts at key attachment points for enhanced longevity. This AR Style handguard utilizes the proprietary Q-Sert interface, which maintains full compatibility with M-LOK accessories, and provides a continuous MIL-STD 1913 Picatinny top rail. The system typically ships as a fully kitted assembly, including a vertical grip, barricade stop, barrel nut, and the necessary drive tools for installation. Note: To ensure proper clearance when using a Q muzzle device or suppressor, a minimum barrel length of 10.3 is recommended for use with this 9-inch handguard.
