Strike Industries GridLok Full Duty 16" M-LOK Handguard for HK 416, HK MR556, M27 IAR

The Strike Industries GridLok Full Duty handguard brings Strike Industries' proprietary quick-change rail system to the HK 416 platform family. Constructed from aluminum with a black finish, this 16" rail features a 1.57" outer diameter and is engineered to be both durable and lightweight for professional use.

The defining feature of the GridLok is Strike Industries' GRIDLOK quick-detach mounting interface, which lets the operator remove and reinstall the entire handguard in seconds without disturbing zeroed optics, lights, or lasers. Integrated M-LOK slots along the sides and bottom provide extensive mounting real estate for accessories like weapon lights, vertical foregrips, laser aiming modules, and bipods. The Full Duty version is specifically designed for law enforcement and special operations communities.

The GridLok Full Duty fits the HK416, HK416 A5, HK416 A7, MR556, and M27 IAR platforms, offering a direct handguard swap with no gunsmithing required. It gives the user a primary, secondary, or multi-setup rail configuration that can be swapped on the fly in the field.
