Strike Industries GridLok Full Duty 9" M-LOK Handguard w/ Quick Detach - HK 416/MR556/M27 IAR

The Strike Industries GridLok Full Duty is a purpose-built 9" M-LOK handguard machined from black aluminum and engineered for the HK 416, HK MR556, and M27 IAR platforms widely adopted by U.S. Law Enforcement and Special Operations units.

Featuring a 1.57" outer diameter profile and an M-LOK slot pattern along its length, the GridLok Full Duty provides a versatile mounting surface for lights, lasers, vertical grips, bipods, and other mission-essential accessories. The integrated Quick Detach (QD) system on the handguard allows push-button sling attachment directly to the chassis, eliminating the need for a separate sling mount.

Specifically designed for the HK 416 / MR556 / M27 IAR upper receiver interface, the Full Duty variant of the Strike Industries GridLok handguard series delivers extended rail coverage for maximum accessory real estate on full-length carbines. The fitment is tailored to the HK 416-pattern platform rather than a standard AR-15/M4 upper.

Finished in black over a lightweight aluminum body, the GridLok Full Duty handguard is built to provide a reliable M-LOK mounting platform with QD sling capability for HK-pattern rifles in the field.
