Description

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.

  • Quick-Detach Rail System with adjustable locking tension

  • Integrated Folding Front Sight (removable for A2 setups)

  • RailLok™ System supports M-LOK and Picatinny 1913 accessories

XTREME Returns

As a small business, we face a choice: we can either raise all of our prices to cover the cost of returns, or we can keep our prices low and offer an optional Return Guarantee. We chose the second option because it's fairer to you. That $5 goes directly toward the logistics of a pre-paid return, meaning you get a "no-questions-asked" experience without us having to inflate the cost of every item in our shop. It keeps us independent and keeps your wallet happy. When you shop with us, your order isn’t just a number—it’s handled by a small team that cares about the gear we sell. Because we don't have the massive overhead of a giant company, we use this $5 guarantee to bridge the gap. It provides you with a pre-paid, priority return path, ensuring that if you need to send something back, we can process it immediately and get your refund or exchange moving. Thank you so much for understanding.
