The Geissele 12.6" MK20 Dual Tab Black Handguard Assembly is a lightweight, modular free-float rail system engineered for AR-15 pattern rifles where rigidity, reduced weight, and flexibility are key. Machined from high-strength 7000 series aluminum and finished in durable Type 3 hardcoat black anodize, the 05-2555B features a dual anti-rotation tab clamp system that securely attaches to the included Geissele proprietary barrel nut, preventing rotation under heavy use. With M-LOK slots at the 3, 6, and 9 o’clock positions and a full-length Picatinny rail at the 12 o’clock position, this handguard offers versatile mounting options for optics and accessories. At approximately 9.7oz (11.4oz with barrel nut) and 12.6in long, it provides a balance of strength and low weight for builds focused on agility and performance.
