GrovTec US GTSW192 M1913 Picatinny Rail - 3.10" 5 Slot Black Aluminum for AR Platform

The GrovTec US GTSW192 M1913 Picatinny rail is a compact 3.10-inch accessory rail built for AR platform rifles. Its standard M1913 Picatinny profile integrates seamlessly with any AR upper receiver or rail system that follows the military-standard spec, giving you flexible mounting options for optics, lights, lasers, and other tactical gear. Black anodized aluminum construction keeps it lightweight without sacrificing durability—a practical addition if you're building out a modular setup or need extra mounting real estate on your carbine.

With five Picatinny slots, this rail delivers genuine utility in a compact footprint. The 3.10-inch length suits AR builds where space is at a premium but you still want more attachment points than your existing rail provides. Whether you're running a close-quarters defensive rifle, a precision AR, or an intermediate hunting platform, a secondary rail lets you dial in light placement, add a backup sight, or mount an offset optic without forcing compromises.

GrovTec's push-button base design simplifies installation and keeps assembly straightforward—no fuss, just bolt-on compatibility with M1913-spec AR platforms. The anodized finish resists corrosion and stands up to field use, so you're not babying it in the safe. If your current AR rail layout is maxed out or you're filling gaps in a modular build, this is honest gear that does what it says.
