Sons of Liberty Gun Works L89A ARCA M-LOK AR-15 16.75″ Black L89A-16.75

The Sons of Liberty Gun Works L89A ARCA M-LOK Handguard 16.75″ (L89A-16.75) is a precision-driven, free-float rail system engineered for shooters who demand maximum rigidity, modularity, and adaptability from their AR-15 platform.

Built around SOLGWs advanced DriveLock mounting system, this handguard delivers an exceptionally strong and secure lock-up by clamping tightly to the included titanium barrel nut, creating a rock-solid interface between the rail and upper receiver. This design enhances durability and consistency, making it well-suited for hard-use and precision rifle applications.

Precision machined from high-quality aluminum and finished in a durable black hard-coat anodizing, the L89A balances strength with weight savings while maintaining long-term resistance to wear and corrosion. Its extended 16.75-inch length provides ample real estate for modern shooting techniques and accessory placement.

The handguard features five-sided M-LOK compatibility, allowing for flexible mounting of lights, grips, and other accessories, while a full-length Picatinny top rail ensures a stable platform for optics and aiming devices. What sets the L89A apart is its integrated full-length ARCA rail along the bottom, enabling direct attachment to tripods and precision shooting supportsideal for PRS-style or long-range setups.

Additional features include integrated steel QD sling swivel sockets for secure sling attachment and strategically placed ventilation cuts to promote airflow and reduce heat buildup during extended firing sessions.

Designed for compatibility with standard AR-15 upper receivers, the L89A handguard represents a premium solution for builders seeking a rugged, feature-rich rail that excels in both tactical and precision shooting environments.
