Sig Sauer M400 Tread MLOK Handguard 13" Black Aluminum Rail

The Sig Sauer HGRDTRDE13MLOKBLK transforms the M400 Tread rifle with enhanced modularity and precision mounting options. This 13-inch handguard delivers the rigid platform needed for consistent accuracy while providing extensive customization capabilities through its MLOK attachment system.

What Makes This Different

Unlike standard plastic handguards, this aluminum construction provides superior heat dissipation and maintains zero under rapid fire conditions. The MLOK interface offers 360-degree mounting flexibility without the added weight of traditional Picatinny rails. Precision CNC machining ensures consistent tolerances and seamless integration with the M400 Tread's upper receiver.

Key Features

• 13-inch length accommodates mid-length gas systems and longer barrel configurations
• 6061-T6 aluminum construction with Type III hard coat anodized finish
• MLOK slots at 3, 6, and 9 o'clock positions for accessory mounting
• Anti-rotation tabs ensure secure lockup with barrel nut
• Continuous top rail maintains sight plane alignment
• Internal diameter optimized for standard barrel profiles
• Compatible with Sig Sauer M400 Tread rifle platform

Field testing demonstrates this handguard maintains accuracy standards even during extended shooting sessions where heat buildup typically affects precision. The aluminum construction dissipates barrel heat more effectively than polymer alternatives, reducing mirage and maintaining consistent point of impact. Competition shooters benefit from the stable platform for bipods and accessories, while tactical applications gain from the lightweight yet rigid mounting system.
