4″ Ultra Lightweight Thin M-LOK Free Floating Handguard With Monolithic Top Rail (Anodized Gold)

Description

This 4-inch ultra lightweight thin M-LOK free floating handguard with monolithic top rail is constructed from T6 aluminum and features an Anodized Gold finish. The unit weighs 6.2 oz including the barrel nut, providing a compact profile for pistol-length builds. The internal diameter measures 1.34 inches, designed to slide over the barrel nut and lock up tightly against the receiver using six screws. The proprietary barrel nut is included in the assembly.

The monolithic top rail ensures a continuous mounting interface, eliminating the gap between the handguard and the upper receiver. This tight fit-up allows for consistent optic alignment and structural rigidity. Thin M-LOK system on the sides and bottom provides multiple attachment points for accessories without the bulk of a traditional rail design. The Anodized Gold finish offers corrosion resistance and a distinct aesthetic, while the T6 aluminum body balances durability with reduced weight.

Made in the USA, this handguard is engineered for precision fitment. The thin profile reduces overall package width, which can be beneficial for shooter comfort and accessory clearance. The solid pattern ensures uniform strength across Top Rail system. Installation involves aligning Top Rail system over the barrel nut and securing it to the receiver. This component is suitable for AR-15 pistol builds requiring a lightweight, compact handguard with integrated mounting options.
