The Strike Industries GridLok Lightspeed handguard (brand part no. GRIDLOK416L16) brings the same quick-detach GRIDLOK system as the Full Duty rail to the HK416, HK MR556, and M27 IAR platform in a trimmed-down, lighter-weight build. Measuring 16 inches long by 1.57 inches in diameter and machined from black aluminum with M-LOK slots, it mounts directly to the factory HK OEM barrel nut using Strike Industries’ patent-pending Quick Rail Detach GRIDLOK locking latch, letting you swap between primary and secondary handguard setups in seconds. It’s built for operators who want the same rapid-swap capability as the Full Duty rail with less weight hanging off the front of the rifle.
