Magpul MOE M-LOK Rifle-Length Handguard AR-15 Gray MAG427-GRY

The Magpul MAG427-GRY MOE M-LOK Rifle-Length Handguard transforms standard AR-platform rifles with a lightweight, modular mounting solution that reduces weight while expanding accessory options. This gray polymer handguard replaces traditional quad rails with M-LOK attachment points positioned exactly where shooters need them most.

What Makes This Different

Unlike bulky quad rail systems that add unnecessary weight and snag on gear, the MOE M-LOK design incorporates attachment points directly into the handguard structure. This approach reduces overall system weight by up to 6 ounces compared to equivalent aluminum quad rails while maintaining the same structural integrity. The rifle-length configuration provides maximum real estate for accessories while ensuring proper gas system alignment on carbine and rifle-length builds.

Key Features

• M-LOK attachment system with multiple positioning options for accessories
• Rifle-length design spans 12.125 inches for maximum accessory mounting space
• Reinforced polymer construction weighs just 7.8 ounces

Field testing demonstrates the MOE M-LOK maintains zero shift during rapid temperature changes and sustained firing. The polymer construction provides natural insulation against barrel heat while the M-LOK slots allow precise accessory positioning for competition shooting, tactical applications, and hunting configurations. Multiple M-LOK positions accommodate lights, grips, bipods, and other accessories without the bulk of continuous rail coverage.
