Geissele Automatics Super Modular Rail MK8 15in M-LOK Free-Float Handguard

Product Description

The Geissele Automatics Super Modular Rail MK8 M-LOK is an ultra-modular, free-float AR-15 handguard built for a strong, rigid mounting platform with excellent heat management. Designed around Magpul M-LOK technology, the MK8 provides accessory mounting at the 3, 6, and 9 oclock positions plus the upper 45-degree quadrants for extensive configurability. Aggressive venting in the lower 45-degree quadrants helps maximize heat dissipation while reducing overall weight for better balance and handling.

The MK8 also uses Geisseles proprietary 2.25-inch long barrel nut to increase surface contact at the receiver interface, helping keep the rail straight and true along the full length. This design supports improved accuracy and repeatable zero when the handguard is removed and reinstalled for maintenance. Barrel nut is included; a Geissele barrel nut wrench is required for installation (sold separately).
