Geissele MK8 Super Modular Rail 9.5" M-LOK Handguard Black

The Geissele Automatics MK8 Super Modular Rail transforms standard AR-15 platforms with precision-engineered modularity and enhanced ergonomics. This 9.5-inch handguard eliminates the bulk of traditional quad rails while providing superior accessory mounting versatility through the M-LOK system.

What Makes This Different

The MK8 features Geissele's proprietary barrel nut system that ensures perfect alignment and eliminates timing issues common with standard handguards. Unlike basic M-LOK rails, the Super Modular design incorporates anti-rotation tabs and enhanced rigidity through strategic material placement. The 6061-T6 aluminum construction provides 40% better strength-to-weight ratio compared to standard 6061 aluminum.

Key Features

• 9.5-inch length accommodates carbine gas systems with suppressor clearance
• M-LOK slots at 3, 6, and 9 o'clock positions for streamlined accessory mounting
• Continuous top rail maintains co-witness with factory sights
• Proprietary barrel nut eliminates timing and provides rock-solid lockup
• Anti-rotation tabs prevent handguard movement under stress
• Type III hard anodized finish resists wear and corrosion
• Compatible with low-profile gas blocks and standard AR-15 upper receivers

Field testing demonstrates the MK8's ability to maintain zero through temperature extremes and high round counts. The slim profile reduces snag points during close-quarters movement while the M-LOK system allows users to position accessories exactly where needed. Competition shooters appreciate the consistent return to zero after accessory changes, while tactical users benefit from the reduced weight compared to quad rail alternatives.
