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

Description

Designed for experienced AR-15 builders, this 4″ Ultra Lightweight Thin M-LOK Free Floating Handguard With Monolithic Top Rail provides a direct-mount solution for upper receiver assembly. Constructed from T6 Aluminum, the body offers a rigid platform while minimizing overall weight. The Unfinished (Blasted) surface treatment leaves the metal in its raw state, allowing for custom finishing or immediate installation in builds where aesthetics are secondary to function.

The handguard features a M-LOK slot pattern, enabling secure attachment of accessories without the bulk of traditional rail sections. It slides over the barrel and locks against the receiver using six screws, ensuring a tight fit that supports the Monolithic Top Rail. This design eliminates flex between Top Rail and the upper receiver, providing a stable optic platform. The internal diameter is specified at 1.34″, compatible with standard AR-15 barrel profiles.

• Includes a Proprietary Barrel Nut for secure mounting.
• Total weight, including the barrel nut, is 6.2 oz.
• Manufactured in the USA to strict tolerances.

This component is intended for use in AR-15 platforms. The 4″ length suits compact builds, while the Heavy Duty construction ensures durability under repeated use. The Unfinished finish requires user discretion regarding corrosion resistance and final appearance.
