Strike Industries GridLok Lightspeed 16" M-LOK Handguard - Black Aluminum for HK 416, MR556, M27 IAR

The Strike Industries GridLok Lightspeed is a 16" free-float handguard purpose-built for the HK 416, HK MR556, and M27 IAR platforms. Machined from aluminum with a black anodized finish, it replaces the factory HK rail with an M-LOK forend that accepts any standard M-LOK accessory or rail section.

At 1.57" in outer diameter, the GridLok Lightspeed provides a full-length mounting platform for weapon lights, lasers, grips, and bipods. The 16" length gives maximum accessory real estate along the barrel, with M-LOK slots on the sides, bottom, and top for tool-less attachment of accessories.

Installation is fast thanks to Strike Industries' signature Quick Detach (QD) system. The handguard mounts directly to the factory HK OEM barrel nut and locks in place in seconds with the patented GridLok locking latch, eliminating the need for shims, timing, or specialty tools. The handguard can be removed and reinstalled as needed.

Designed and finished by Strike Industries, the GridLok Lightspeed is built for HK-pattern rifle operators who want a more accessorizable forend. It is a direct replacement for the OEM rail on compatible HK 416, MR556, and M27 IAR rifles.
