This is the Strike Gridlok Handguard (PRE-ASSEMBLED). It comes in four different lengths for the modern shooter to pick and choose based on their mission or intended use. Strike Industries has always been passionate about pushing the boundaries for innovative solutions and the Gridlok is a great product that embodies that ethos.

The GRIDLOK Handguard was made for the AR platform and is our first quick detachable M-LOK handguard featuring full modular colorways (different product page) with integrated backup sights, built-in picatinny mounts, and a spring loaded detach lever for the QUICKEST rail removal process ever. The QD Locking lever allows for rapid detachment of the rail housing from the barrel nut.

Made out of 6061 aluminum from precision CNC milling, the Gridlok is durable and has a semi-matte finish for the smooth finish. Using 7250 anodized aluminum, its barrel nut provides a lightweight solution that's proprietary to our GRIDLOK system.

Featuring our patented RaiLok Mounting System, the GRIDLOK combines the versatility of M-LOK with ample picatinny slots to cater towards multiple accessories' mounting platforms. It gives the user the best of both worlds and allows for endless customization for attachments and configurations.

Of course, with a larger internal diameter of 1.6" the GRIDLOK is built to accommodate mid to large concussion reduction devices (such as our Oppressor) so that you can recess them into the handguard to have that sleek and streamlined build.
