Sons of Liberty Gun Works M76 M-LOK Handguard

The Sons of Liberty Gun Works M76 M-LOK Handguard is a rugged, free-float rail engineered for shooters who demand a rigid mounting system without unnecessary weight. Utilizing SOLGW's proprietary wedge-lock design, the M76 securely clamps to its steel barrel nut while pulling the handguard tightly against the upper receiver, creating an exceptionally solid lockup that resists movement under hard use.

Whether you're building a duty rifle, defensive carbine, or a dependable range gun, the M76 delivers the strength, reliability, and clean aesthetics that SOLGW is known for.

Built for Reliability

The M76's proprietary wedge-lock system creates an exceptionally secure interface between the handguard, barrel nut, and upper receiver. This design minimizes movement under recoil and hard use while maintaining excellent rigidity for mounted accessories such as weapon lights, lasers, and bipods.

Combined with its steel barrel nut and precision machining, the M76 provides the confidence serious shooters expect from a premium handguard.

Our Thoughts

The M76 helped establish Sons of Liberty Gun Works as one of the premier manufacturers of hard-use AR components.

It's simple, lightweight, incredibly rigid, and designed with function over gimmicks. The integrated QD socket, full-length Picatinny rail, and generous M-LOK mounting surfaces provide everything most shooters need without adding unnecessary bulk.

If you're deciding between the M76 and the newer M89, the M89 offers increased rigidity and a larger internal diameter thanks to its DriveLock™ system. However, the M76 remains an outstanding choice for shooters looking for a proven, lightweight handguard that has earned an excellent reputation on duty and defensive rifles.
