Midwest Industries G4M M-LOK 13.375" Handguard

Midwest Industries Gen 4 M-Series Handguard

The Gen 4 M-Series represents the evolution of modern AR-15 handguard design—a purpose-built accessory rail system that balances form and function without compromise.

Design and Construction

This handguard exemplifies precision engineering. The slim profile measures just 1.5" outside diameter with a 1.3" inside diameter, keeping your rifle balanced and maneuverable. The 6061 aluminum construction receives a Type 3 hard coat anodize finish, providing durability and corrosion resistance that will serve you through years of use.

Mounting and Compatibility

The handguard features a continuous MIL-STD 1913 Picatinny rail along the top, giving you unlimited mounting options for optics, lights, and other tactical accessories. Seven sides of M-LOK slots provide flexible accessory mounting without the bulk of full-length rails. Five integral anti-rotation QD sling sockets ensure your sling stays exactly where you position it.
