Geissele Super Modular MK4 AR-15 Handguard - M-LOK - 9.3"

The Geissele Automatics Super Modular MK4 AR-15 handguard is an ultra-light, purpose-built free float rail for shooters who want maximum venting and modularity in one package. Built for the M4 carbine and mil-spec AR-15 variants, this handguard keeps weight down without giving up rigidity.

Features:

• M-LOK slots on five sides for accessory mounting and heat dissipation
• Integral M1913 rail sections at the 3, 6, and 9 o'clock positions near the muzzle end for lights and bipods
• Full-length M1913 Picatinny top rail
• 7000-series aluminum construction
• 2" long proprietary Geissele barrel nut (wrench not included)
• 9.3" length
• 11.0 oz installed weight

The M-LOK slots double as ventilation, cutting weight while keeping the rail cool under sustained fire. Geissele's proprietary 2" long barrel nut increases surface contact between the rail and receiver, giving you a platform that stays straight and true so zero holds through disassembly and reassembly during routine maintenance.

Founded in 2004 by Bill Geissele in Pennsylvania, Geissele Automatics built its reputation on precision AR-15 triggers before expanding into rail systems and other combat-proven components. The company's Super Modular Rail line has been adopted by U.S. Special Operations Command, reflecting the same engineering rigor Geissele applies across its entire product line.
