Strike Industries GridLok AR-15 Picatinny Handguard Review

Why the Strike Industries GridLok AR-15 Picatinny Handguard Might Be Right for You

The Strike Industries GridLok AR-15 Picatinny Handguard is a modular component designed to enhance the versatility and accessory mounting capabilities of AR-15 platforms. It’s crafted from rugged 6061 aluminum with a semi-matte finish, promising a durable yet comfortable interface. The core innovation lies in its RailLok mounting system, which ingeniously accommodates both Picatinny 1913 and M-LOK accessories.

My journey to this handguard began with a specific need for my 300 Blackout build. I was looking for a robust and adaptable handguard that wouldn’t limit my accessory choices, particularly for mounting a suppressor adapter. The existing options on my rifle felt restrictive, and I wanted a solution that offered more flexibility.

Upon initial inspection, the GridLok handguard impressed me with its solid construction and thoughtful design. The 6061-T6 aluminum felt substantial, and the semi-matte finish offered a pleasant grip. I had briefly considered a few other premium brands, but Strike Industries’ reputation for innovative AR accessories and the unique RailLok system ultimately swayed my decision.

My first reaction was one of pragmatic optimism; it seemed like a well-engineered piece that could solve my accessory mounting challenges.

Real-World Testing: Putting Strike Industries GridLok AR-15 Picatinny Handguard to the Test

My primary testing environment for the GridLok was my home workshop and the local shooting range, specifically for a 300 Blackout build. This AR platform is often used for a mix of static target practice and dynamic drills, requiring reliable and easily accessible accessory integration. I attached various items, including weapon lights, vertical grips, and a laser aiming module, to assess the handguard’s mounting system.

In terms of performance, the handguard handled repeated accessory installations and removals with ease. The RailLok system maintained a secure grip on both Picatinny and M-LOK attachments throughout multiple range sessions. Even under the recoil of a .300 Blackout, none of the mounted accessories shifted.

Ease of use was surprisingly high; the instructions were clear, and the proprietary tools provided made installation straightforward. The only minor hiccup was the initial tightening of the QD Locking Lever, which required a bit of adjustment to find the perfect balance between secure and easily adjustable.

Over an extended period of use, approximately six months of regular range visits and workshop tinkering, the GridLok has held up remarkably well. There are no visible cracks, significant scuffs, or performance degradation to report. The anodized finish has proven resilient against minor bumps and scrapes.

Maintenance is relatively simple: a quick wipe down with a mild solvent and a soft cloth keeps it looking fresh. I did notice that the internal clearance, a generous 1.6 inches, was perfect for accommodating my suppressor blast shield, something not all handguards offer. Compared to previous handguards I’ve used, this one offers a superior combination of modularity and a secure grip.

First Use Experience

My initial installation of the Strike Industries GridLok handguard was on a dedicated 300 Blackout AR-15 build. I performed the installation on my workbench, utilizing a standard AR-15 armorer’s bench block and torque wrench. The process was generally straightforward, thanks to the included instructions and the proprietary magnetic tool for the retention caps.

The handguard performed admirably during its first range outing. I mounted a tactical flashlight and a BCM vertical grip, both of which remained rock solid throughout several magazines of ammunition. The semi-matte finish offered a comfortable and non-slip surface, even with slightly sweaty hands after a few shooting strings.

The only slight annoyance was the aforementioned magnetic tool; while a nice touch for holding small screws, its magnetic strength could have been a bit more robust. A couple of times, I had to re-seat a retention cap screw that had dislodged itself from the tool. This is a minor quibble, however, and did not detract from the overall positive initial experience.

Extended Use & Reliability

After consistent use over several months, the Strike Industries GridLok AR-15 Picatinny Handguard has proven its mettle. It has been subjected to varying weather conditions, from cool autumn days to warmer spring afternoons, and has maintained its structural integrity and finish. The 6061-T6 aluminum construction continues to exhibit excellent durability.

I’ve swapped out accessories a few times to test the RailLok system’s versatility, and each time, the mounting points have held their tension without issue. The internal rail clearance of 1.6 inches has been a significant benefit for users with larger barrel diameters or suppressor-ready setups, allowing ample room for various accessories.

Cleaning involves simply wiping it down with a dry cloth or a mild degreaser. There have been no signs of loosening or degradation in its ability to hold accessories securely. It’s a testament to the Strike Industries engineering that this component has remained so reliable.
