The Geissele 12.6" MK20 Dual Tab DDC Handguard Assembly is a modular free-float rail system engineered for AR-15 pattern rifles where a balance of rigidity, weight savings, and accessory mounting flexibility is desired. Built from high-strength 7000 series aluminum and finished in durable Desert Dirt Color (DDC) Type 3 hardcoat anodize, this 12.6 inch handguard employs a dual anti-rotation tab clamp system that securely engages the included proprietary Geissele barrel nut to prevent rotation under heavy use. With M-LOK slots at the 3, 6, and 9 o’clock positions and a continuous Picatinny rail at the 12 o’clock position, it offers robust mounting options for optics, lights, grips, and other accessories. The assembly maintains a slim, lightweight profile while delivering the strength and versatility expected from Geissele’s MK20 platform. Geissele 12.6" MK20 Dual Tab DDC Handguard Assembly 05-2555S
