Geissele MK8 Super Modular Rail 15" DDC Aluminum M-LOK Handguard

The Geissele Automatics MK8 Super Modular Rail transforms AR-15 platforms with precision-machined aluminum construction and advanced M-LOK attachment system. This 15-inch handguard delivers the rigidity and mounting flexibility that competitive shooters and tactical professionals demand from their rifle systems.

What Makes This Different

The MK8 features Geissele's proprietary barrel nut system that creates a stronger interface than standard delta ring assemblies. Machined from 6061-T6 aluminum with Type III hard coat anodizing in Desert Dirt Color (DDC), this rail system weighs just 11.5 ounces while maintaining exceptional strength-to-weight ratios. The continuous top rail and anti-rotation tabs ensure consistent zero retention through thousands of rounds.

Key Features

• 15-inch length accommodates mid-length and rifle-length gas systems
• M-LOK slots at 3, 6, and 9 o'clock positions for accessory mounting
• 6061-T6 aluminum construction with Type III hard coat anodizing
• Proprietary barrel nut system eliminates timing issues
• Anti-rotation tabs prevent handguard movement under stress
• Compatible with low-profile gas blocks and standard AR-15 uppers
• Desert Dirt Color finish matches Geissele triggers and components

Field performance demonstrates the MK8's ability to maintain zero through rapid temperature changes and sustained fire schedules. The extended length provides additional real estate for bipods, lights, and laser devices while keeping accessories away from the muzzle blast. Law enforcement agencies report consistent accuracy improvements when upgrading from carbine-length plastic handguards to this system.
