The GrovTec US GTSW230 6" 15-Slot M1913 Picatinny Rail gives you a straightforward way to add standard Picatinny-mount accessories to your AR-platform rifle. Built from black anodized aluminum, this 6-inch rail is designed to work with KeyMod slots on your handguard or receiver, letting you mount optics, lights, laser units, or other gear without having to swap out your entire rail system. It's the kind of no-frills upgrade that working shooters appreciate—solid, compatible, and focused on getting the job done.
Whether you're setting up a tactical rifle, a hunting AR, or a competition gun, having extra Picatinny real estate is always useful. The 15 slots give you plenty of flexibility to position your accessories exactly where you want them. The aluminum construction keeps weight down while maintaining the rigidity you need for repeatable accuracy. Black anodizing resists corrosion and blends with most modern AR builds.
If your current handguard or rail system uses KeyMod attachment points, this GrovTec rail lets you leverage standard Picatinny-mount accessories—a huge advantage if you've already invested in optics and lights with Picatinny footprints. Installation is straightforward, and the design is proven across thousands of AR builds in the field and at the range.

Frequently Asked Questions
Will this rail work with my AR handguard?
The GTSW230 is designed to attach to KeyMod slots, so your handguard or rail system must have KeyMod mounting points. If your setup uses Picatinny slots or M-LOK instead, this rail won't be the right fit.
What kind of accessories can I mount on this rail?
Any accessory with a standard M1913 Picatinny footprint will work—that includes tactical lights, lasers, optic mounts, vertical grips, and other rail-mounted gear. The 15 slots give you plenty of space to arrange them however you need.
Is this rail compatible with AR-15 and AR-10 platforms?
The GTSW230 attaches to KeyMod slots, which are used on both AR-15 and AR-10 rifles. As long as your rifle has KeyMod mounting points on the handguard or receiver, it will work.
How does black anodizing affect durability?
Black anodizing is an electrochemical process that hardens the aluminum surface and resists corrosion, scratches, and wear. It's standard on modern AR accessories and holds up well to field use and harsh conditions.
