Description

Engineered for experienced AR-15 builders, this 15-inch Ultra Lightweight Thin M-LOK System Free Floating Handguard With Monolithic Top Rail (Unfinished) delivers a rigid, precision interface for upper receiver assembly. The unit is constructed from T6 Aluminum with a raw, blasted finish, providing a durable foundation for custom finishing or immediate use in builds requiring a specific aesthetic. The total weight including barrel nut is 10.8 oz, ensuring minimal added mass to the front of the platform without sacrificing structural integrity.

The handguard features an internal diameter of 1.34″, allowing for compatibility with various barrel profiles while maintaining free-float operation. It utilizes a proprietary barrel nut design that allows Top Rail system to slide over the barrel and lock up tightly against the receiver using six screws. This tight fit ensures the monolithic top rail remains perfectly aligned with the upper receiver, providing a stable mounting surface for optics and accessories.

Key specifications include the M-LOK System on the sides for modular attachment of grips, lights, and other accessories, and a Monolithic Top Rail that integrates seamlessly with the handguard body. The unit is US Made, adhering to domestic manufacturing standards for quality control. The 15″ Extended Length offers ample space for hand placement and accessory mounting while maintaining a slim profile that fits comfortably within most standard cases and bags. The heavy-duty construction ensures it can withstand the rigors of regular use while remaining ultra lightweight for improved handling.

This product is supplied as an Unfinished component, allowing for customization via anodizing or other finishing methods. The raw blasted surface provides excellent adhesion for coatings. The included barrel nut is proprietary to this design, ensuring a secure and precise fit that cannot be compromised with generic parts. The combination of the thin profile, M-LOK slots, and monolithic rail makes this a versatile choice for builders seeking a balance of weight savings and modularity.
