Ultra Lightweight Construction

Precision CNC machined from premium T6 aluminum, this handguard is engineered to remove unnecessary weight while maintaining excellent rigidity. Weighing approximately 10.8 ounces including the proprietary barrel nut, it helps reduce front-end weight without sacrificing strength.

Monolithic Top Rail

The handguard fits tightly against the upper receiver, creating a seamless monolithic Picatinny top rail. This continuous rail provides a stable mounting surface for optics, backup sights, lasers, and other Picatinny-compatible accessories while maintaining proper alignment.

M-LOK Accessory Mounting

Integrated M-LOK slots provide flexible mounting options for modern accessories while maintaining a slim, comfortable profile.

• Weapon lights
• Vertical and angled foregrips
• Hand stops
• Bipods
• Sling mounts
• Other M-LOK accessories

True Free Float Performance

As a true free float handguard, the rail attaches only to the included proprietary barrel nut without contacting the barrel. This design helps improve barrel harmonics, consistency, and overall accuracy while reducing the influence of mounted accessories on barrel movement.

Secure Locking System

The handguard slides over the included proprietary barrel nut and locks securely against the upper receiver using six mounting screws. This heavy-duty attachment system provides excellent rigidity and dependable long-term performance.
