Strike Industries GRIDLOK416L16 Lightspeed 16" M-LOK Handguard with Quick Detach System for HK 416/MR556/M27 IAR - Black Aluminum

The Strike Industries Lightspeed 16" M-LOK handguard is engineered for shooters running HK 416, MR556, or M27 IAR platforms who demand modularity without compromise. This black aluminum rail system combines a streamlined profile with genuine tactical versatility—you get full M-LOK compatibility for mounting optics, lights, grips, and other accessories exactly where you need them, plus an integrated quick detach system for rapid configuration changes in the field or at the range.

Strike Industries built the Lightspeed around the idea that your handguard shouldn't be a weight penalty. At 16 inches, it spans most of your sight line and provides excellent real estate for gear without adding unnecessary bulk. The M-LOK mounting standard has become the industry default for good reason: it's strong, repeatable, and lets you swap accessories without tools. The included quick detach capability means you can transition setups fast—swap between a hunting configuration and a duty setup without breaking down the whole rifle.

This handguard is built from aluminum, chosen for its strength-to-weight ratio and corrosion resistance. Whether you're running a tac rifle, duty gun, or a well-tuned SPR, the Lightspeed integrates seamlessly into HK's piston-driven ecosystem. It's the kind of component that disappears into a quality build and just works—no rattle, no flex, no compromises.
