The Q LLC Q-Sert AR Handguard is an ultra-compact 6 free-float rail system engineered for high-performance AR-15 platforms. Precision-machined from high-strength aluminum with a signature Clear Coat Anodized finish, it features integrated stainless steel inserts at key attachment points for enhanced durability. This AR Style handguard utilizes the proprietary Q-Sert interface, which offers dual compatibility with both Q-Sert and standard M-LOK accessories. Designed with a superior stiffness-to-weight ratio, this 6 rail includes a continuous MIL-STD 1913 Picatinny top rail and typically ships as a full kit with a vertical grip, barricade stop, and all necessary mounting hardware. Note: This 6-inch handguard is optimized for extremely short PDW style builds. When selecting a muzzle device or suppressor, ensure the barrel length provides adequate clearance to avoid damaging the handguard.
