Geissele Super Modular Rail HK416 14.5" Black Aluminum Handguard

The Geissele Automatics Super Modular Rail transforms the HK416 platform with precision-engineered aluminum construction and enhanced modularity. This 14.5-inch rail system delivers the rigidity and accessory mounting flexibility that professional users demand from their primary weapon system.

What Makes This Different

Geissele's proprietary barrel nut design creates a monolithic upper receiver extension that eliminates flex under stress. The rail maintains zero even when mounting heavy accessories like suppressors or bipods. Unlike standard quad rails, the SMR's selective picatinny placement reduces weight while maintaining full modularity where operators need it most.

Key Features

• Precision-machined 6061-T6 aluminum construction with Type III hard coat anodizing
• 14.5-inch length provides full coverage for 14.5" and 16" barrel configurations
• Proprietary barrel nut system creates rock-solid lockup with HK416 upper receivers
• Strategic picatinny rail sections at 3, 6, and 9 o'clock positions
• M-LOK compatible slots throughout for modern accessory attachment
• Anti-rotation tabs prevent rail movement under heavy use
• Mil-spec dimensions ensure compatibility with standard HK416 components

Field testing demonstrates the SMR's ability to maintain point of impact consistency through temperature extremes and high round counts. The rail system handles the thermal stress of rapid-fire sequences without shifting zero or loosening hardware. Law enforcement and military units report reliable performance in desert, arctic, and maritime environments.
