Midwest Industries G4M 10.5" M-LOK Handguard AR-15 Aluminum Black

The Midwest Industries G4M 10.5-inch handguard transforms standard AR-15 platforms into versatile tactical rifles. This aluminum handguard delivers the mounting flexibility and heat dissipation needed for extended shooting sessions. Built with precision-machined 6061-T6 aluminum, the G4M series represents proven engineering in modern rifle accessories.

What Makes This Different

The G4M handguard features a continuous top rail that maintains sight alignment with the upper receiver. Unlike basic polymer guards, this aluminum construction disperses barrel heat effectively during rapid fire sequences. The M-LOK attachment system provides secure accessory mounting at multiple positions without adding unnecessary weight or bulk to the rifle platform.

Key Features

• 10.5-inch length optimized for carbine and SBR configurations
• 6061-T6 aluminum construction with Type III hard anodized finish
• Full-length Picatinny top rail for optics and backup sights
• M-LOK slots at 3, 6, and 9 o'clock positions for accessories
• Anti-rotation tabs prevent handguard movement under stress
• Compatible with low-profile gas blocks and standard barrel nuts
• Weighs 8.2 ounces for balanced handling characteristics

Field performance shows consistent accuracy maintenance even during high round count sessions. The aluminum construction conducts heat away from the barrel faster than polymer alternatives, maintaining zero stability. Competition shooters benefit from the rigid platform for bipods and grips, while tactical users appreciate the multiple attachment points for lights and lasers. The black anodized finish resists corrosion in humid environments and maintains its appearance through thousands of rounds.
