Strike Industries GRIDLOK 11" Full Duty M-LOK Handguard for HK 416/MR556/M27 IAR - Black Aluminum

The Strike Industries GRIDLOK 11" Full Duty M-LOK handguard is purpose-built for HK 416, MR556, and M27 IAR platforms. If you're running one of these rifles and want a lightweight, modular forend that doesn't compromise on real estate for mounting optics, lights, and other combat gear, this is your answer. The 11-inch length strikes a practical balance—long enough to give you solid hand placement and rail space, short enough to keep the rifle pointable in tight spaces. Black anodized aluminum construction keeps weight down while holding up to hard use.

Strike Industries designed the GRIDLOK with M-LOK slots throughout, meaning you can attach gear exactly where you need it without buying proprietary mounts. The Full Duty designation tells you this isn't a minimalist rail; it's built to handle duty cycles and real-world abuse. Whether you're setting up a patrol rifle, a precision intermediate build, or a modular platform you'll actually train with, the GRIDLOK gives you the adaptability modern shooters expect.

Installation is straightforward on compatible HK platforms. The aluminum construction resists corrosion and abuse, and the anodize finish won't snag on kit or your gear in the field. This is the kind of accessory that earns its place on your rifle through quiet reliability rather than flashy marketing.
