Midwest Industries G4 M-Lok Handguard 15" Black

The Midwest Industries G4 M-Lok Handguard 15" Black is a free-floating aluminum rail system engineered for AR-platform carbines and mid-length build configurations. At 15 inches in overall length with a super-slim 1.5" outer diameter profile, this handguard delivers a lightweight, ergonomic solution for operators requiring extended mounting real estate without excessive weight penalty or hand fatigue during extended shooting sessions or tactical operations.

Construction centers on 6061 aluminum with Type 3 hard coat anodizing, providing corrosion resistance and durability across diverse environments. The handguard features a continuous MIL-STD 1913 Picatinny rail across the top for optic mounts, accessory rails, or magnification systems, complemented by seven sides of integrated M-Lok slots for streamlined accessory placement. The patented 4140 heat-treated torque plate ensures predictable barrel nut seating and eliminates rotation during installation and sustained fire. At 11.5 ounces installed weight, the G4 maintains the low-inertia characteristics essential for balance and recoil management on mid-weight platforms.

Five integral quick-detach sling sockets provide flexible attachment points for single-point, two-point, or hybrid sling configurations without requiring separate rail-mounted hardware. The slim 1.3" inner diameter accommodates standard AR-15 gas tubes while maintaining ergonomic hand positioning during precision work or tactical employment. The included barrel nut and installation wrench streamline setup, reducing assembly time and ensuring proper torque specification from the outset.

This configuration suits precision rifle builds, duty carbines, 3-gun competition platforms, and general-purpose AR systems where balanced weight, modular accessory mounting, and field-proven reliability define the requirements. The M-Lok ecosystem offers compatibility with a comprehensive aftermarket of tactical lights, vertical grips, rail sections, and covers.
