The Strike Industries Gridlok-416-L-11 Gridlok Lightspeed With Quick Detach System is a purpose-built handguard for HK416, HK416 A5/A7, MR556, and M27 IAR platforms. Machined from lightweight aluminum, this 11 inch, 1.57 inch diameter M-LOK rail uses Strike’s patent-pending Gridlok quick rail detach latch, allowing rapid removal and reinstallation while maintaining a solid, repeatable lockup on the factory HK barrel nut.

This model is ideal for shooters who want fast configuration changes, accessory mounting flexibility, and a slimmer profile on their duty or range rifle. The integrated M-LOK slots and top rail section support lights, grips, and other accessories, while the quick detach design lets you swap between the Gridlok and standard HK rail in seconds. It reflects Strike’s focus on practical innovation and precise machining for modern rifle platforms.
