The Strike Industries GridLok Full Duty Rail for HK 416 (SI-GRIDLOK-416-FD-11) is a precision-engineered, single-piece free-float handguard built specifically for Law Enforcement and Special Operations communities who depend on the HK416, HK MR556, and M27 IAR platforms. Machined from 6061-T6 aluminum, this 11-inch rail integrates Strike Industries' patent-pending Quick Rail Detach GRIDLOK locking latch, enabling operators to rapidly swap or reinstall the handguard directly onto the factory HK OEM barrel nut with no additional tools required. Whether deployed as a primary handguard replacement or as part of a multi-rail configuration, the GridLok Full Duty delivers exceptional rigidity, reduced weight, and comprehensive accessory mounting capability for the most demanding operational environments.
