Daniel Defense RIS II M4A1 FSP Handguard

The Rail Interface System (RIS II) represents a proven design born from real-world operational requirements. Originally developed for the United States Special Operations Command's SOPMOD II program, this handguard delivers the modularity and precision that professional shooters demand.

Key Features

• Free-Floating Design: Allows independent movement of the barrel for improved accuracy and consistency
• Picatinny Rail System: Comprehensive rail coverage for mounting optics, lights, lasers, and other accessories
• FSP Compatibility: Engineered cutout accommodates standard front sight bases on carbine-length gas systems
• Robust Construction: Machined from 6061-T6 aluminum for strength without excess weight
• Flat Dark Earth Finish: Durable anodized coating in a professional, neutral tone
• 12.25" Length: Provides excellent hand placement and accessory mounting real estate

Performance and Reliability

The RIS II handguard's free-floating barrel design eliminates contact between the barrel and handguard, reducing harmonic vibrations that can affect shot placement. This translates to tighter groups and more predictable performance across different shooting conditions.

The modular rail system gives you complete control over your rifle's configuration. Whether you're setting up for tactical training, competition, or duty use, the RIS II adapts to your specific needs.
