6″ AIR-LOK Series M-LOK Compression Free Floating Handguard With Monolithic Top Rail (Anodized Blue)

Description

The 6″ AIR-LOK Series M-LOK Compression Free Floating Handguard delivers a rigid, monolithic top rail interface for AR-15 platforms. Constructed from T6 Aluminum and finished in Anodized Blue, this component utilizes a compression lock-down design to secure Top Rail system firmly against the receiver. The unit weighs 6.2 oz including the barrel nut, a weight optimized through triangle and diamond skeletonized cuts that remove material without compromising structural integrity. The handguard features M-LOK slots on the bottom, left, and right sides, providing a standardized mounting ecosystem for accessories. Its internal diameter is 1.32″, ensuring compatibility with standard barrel profiles. The proprietary barrel nut is included, facilitating a tight fit-up that allows Top Rail system to slide over the nut and compress down against the receiver with four screws. This method ensures the handguard remains free-floating, isolating the barrel from external pressure while maintaining a solid anchor point for optics and attachments. Key specifications include a 6″ length, Anodized Blue finish, and T6 Aluminum body construction. The monolithic top rail offers a continuous Picatinny surface, eliminating the gap found in traditional handguard designs. This design is ideal for builders requiring a stable optic platform and modular accessory mounting in a compact form factor. The unit is made in the USA, ensuring consistent manufacturing quality for critical upper receiver components.
