Geissele Automatics Super Modular MK8 Rail AR-15 Handguard - M-LOK - ODG - 9.3"

The Geissele Super Modular MK8 Handguard is a lightweight, rugged 9.3" free-float rail built for maximum modularity and performance. Finished in OD Green with a Type-3 hardcoat anodize, this rail uses 7000 Series aluminum for exceptional strength without added weight.

Featuring M-LOK slots at the 3, 6, and 9 o’clock positions, the MK8 allows for full accessory customization while maintaining structural rigidity. Aggressive venting at the lower 45° angles improves heat dissipation and reduces overall weight.
