Magpul MOE SL Handguard AR-15 Mid-Length FDE Polymer MAG538

The Magpul MOE SL Handguard delivers streamlined protection and mounting versatility for AR-platform rifles without the bulk of traditional quad rails. This mid-length handguard features Magpul's signature Flat Dark Earth polymer construction, providing excellent heat resistance while maintaining a lightweight profile that won't shift your rifle's balance point.

What Makes This Different

Unlike heavy aluminum rail systems, the MOE SL uses a sleek polymer shell with integrated M-LOK slots positioned at the 3, 6, and 9 o'clock positions. The design eliminates sharp edges and unused rail space while maintaining full compatibility with M-LOK accessories. Heat buildup stays manageable even during rapid fire sequences, thanks to the polymer's natural insulating properties and ventilation channels.

Key Features

• Mid-length design fits carbine gas systems with 9-inch handguard space
• M-LOK slots at 3, 6, and 9 o'clock positions for accessory mounting
• Reinforced polymer construction weighs 6.8 ounces versus 12+ ounces for quad rails
• Drop-in installation requires no special tools or gunsmithing
• Flat Dark Earth finish matches Magpul furniture and military equipment
• Anti-rotation tabs prevent shifting under heavy use
• Compatible with standard AR-15/M4 delta ring assemblies

Range performance shows the MOE SL maintains zero consistency across temperature changes better than metal alternatives. The polymer construction dampens vibration transfer from the barrel, contributing to shot-to-shot precision in both precision rifle applications and rapid-fire scenarios. Law enforcement agencies report excellent durability through thousands of training rounds, while competitive shooters appreciate the reduced weight for extended match stages.
