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

Description

This 4″ Ultra Lightweight Thin M-LOK Free Floating Handguard is manufactured in the USA, providing a rigid platform for AR-15 upper receivers. The unit features Monolithic Top Rail that slides over the barrel nut and locks directly against the receiver with six screws, ensuring a tight fit and consistent alignment for optics. This design eliminates the need for separate rail segments by integrating the top rail directly into the handguard body.

Constructed from T6 Aluminum with an Anodized Grey Finish, the handguard offers a durable surface while maintaining a low profile. The internal diameter is specified at 1.34″, which is critical for ensuring proper clearance around the gas tube and barrel. The total weight, including the Proprietary Barrel Nut, is 6.2 oz, making it a suitable choice for builders prioritizing a lighter upper assembly. Thin M-LOK slots along the sides and bottom allow for modular attachment of accessories such as grips or lights.

The handguard is designed for AR-15 platforms and utilizes a Pistol Length gas system interface. The included Proprietary Barrel Nut ensures correct headspace and timing during installation. The solid pattern provides a robust surface for screw retention, while the thin profile reduces overall bulk. This component is intended for use by knowledgeable builders who understand the specific fitment requirements of AR-15 upper receivers and gas systems.
