Magpul MOE SL Mid-Length Handguard MAG551 FDE AR-15 Polymer

The Magpul MOE SL Mid-Length Handguard delivers streamlined ergonomics and enhanced control for AR-platform rifles. This polymer handguard reduces weight while maintaining structural integrity for demanding applications. Built with Magpul's reinforced polymer construction, it provides a secure mounting platform without the bulk of traditional quad-rail systems.

What Makes This Different

The MOE SL design eliminates unnecessary material while preserving strength through strategic reinforcement points. Unlike standard plastic handguards, this system incorporates steel heat shields and reinforced mounting points rated for extended firing sessions. The mid-length configuration optimizes gas system performance and provides 9 inches of rail space for accessories. Weight reduction of approximately 6 ounces compared to quad-rail alternatives improves handling characteristics.

Key Features

• Mid-length design fits carbine gas system AR-15 rifles with 16-inch barrels
• Flat Dark Earth polymer construction resists impact and temperature extremes
• Integrated steel heat shields protect against barrel heat during rapid fire
• M-LOK compatible slots at 3, 6, and 9 o'clock positions for accessories
• Anti-rotation tabs ensure secure barrel nut interface
• Ambidextrous sling attachment points built into forward section
• Compatible with standard AR-15 delta ring and handguard cap assembly

Field testing demonstrates consistent performance across temperature ranges from -30°F to 140°F without dimensional changes. The polymer material maintains grip texture in wet conditions while resisting scratches and impacts common in tactical environments. Installation requires no special tools beyond standard armorer's equipment. The handguard maintains zero shift during extended firing sessions due to the steel-reinforced mounting system.
