Description


This Ultra Lightweight M-LOK Free Float Handguard is engineered for shooters who demand maximum rigidity, minimal weight, and clean monolithic alignment across a wide range of AR builds. Proudly made in the USA, this handguard is designed to deliver strength and precision without unnecessary bulk.

Machined from 6061 T6 aluminum, the rail features a tight, receiver-hugging interface that creates a monolithic top rail appearance, ensuring consistent optic alignment and enhanced structural rigidity. The handguard slides over the included proprietary barrel nut and locks firmly against the receiver using six heavy-duty mounting screws, resulting in a secure, no-shift free-float system.

Despite its strength, this handguard remains exceptionally light. Even in longer configurations, the rail maintains excellent balance, making it ideal for lightweight builds, duty rifles, and performance-oriented setups. The M-LOK mounting system allows for flexible accessory placement while keeping the profile slim and snag-free.

With an internal diameter of 1.34″, the handguard clears most low-profile gas blocks with ease. Available in a wide range of lengths, this system supports everything from compact PDW-style builds to full-length rifles. Anodized for corrosion resistance and durability, this rail delivers both function and clean aesthetics.

Compatible with 5.56 and 9mm AR platforms, this handguard offers a versatile solution for nearly any modern AR configuration.
