Strike Industries GRIDLOK Complete AR-15 Handguard

The Strike Industries GRIDLOK Complete Handguard is a next-generation AR-15 rail system engineered for shooters who demand maximum modularity, rapid removal, and modern ergonomics. After over two years of development, the GRIDLOK delivers Strike Industries’ first true quick-detach M-LOK handguard, combining a slim profile with integrated backup sights and proprietary RailLok™ mounting technology.

Precision CNC-machined from 6061-T6 aluminum, the GRIDLOK features a spring-loaded QD locking lever that allows the entire rail housing to be removed from the barrel nut in seconds. The proprietary 7250 anodized aluminum barrel nut reduces weight while maintaining strength and repeatable alignment.

With a 1.6″ internal diameter, the GRIDLOK accommodates mid-to-large muzzle devices and blast diffusers, including the Strike Oppressor. Integrated RailLok™ slots combine the low profile of M-LOK with the rigidity of Picatinny, giving you flexible mounting without added bulk.

Available in multiple lengths and modular colorways, the GRIDLOK is ideal for duty rifles, competition builds, suppressor-ready setups, and advanced custom AR projects.
