The Geissele 9.3" Super Modular MK4 M-LOK Handguard is an ultra-lightweight option designed for AR platforms. It features integrated short M1913 picatinny rail sections at the 3, 6, and 9 o'clock positions for added versatility. The maximum venting design allows for heat dissipation while significantly reducing overall weight, ensuring a strong and rigid platform. The handguard utilizes Magpul's M-LOK technology for mounting accessories and includes Geissele's proprietary 2.25" long barrel nut that enhances surface contact with the receiver, promoting accuracy and zero repeatability during maintenance. A Geissele barrel nut wrench is required for installation (sold separately).
