The GrovTec US M1913 Picatinny rail for AR-platform rifles bridges the gap between modern M-LOK handguards and your favorite Picatinny-mounted optics and accessories. If you've invested in a quality M-LOK handguard but want to run lights, lasers, or other rail-based gear, this 3.80-inch, 9-slot adapter gives you that flexibility without forcing a handguard swap. It's a straightforward solution for shooters who want to standardize their accessory ecosystem across multiple rifles.

Built from lightweight aluminum with a hardcoat black anodized finish, this rail maintains the durability you need on a working rifle while staying trim on your setup. The MIL-STD 1913 pattern ensures compatibility with the broad universe of Picatinny-mounted accessories—whether you're adding a pressure switch for a tactical light, mounting a laser for low-light work, or integrating other modular gear. GrovTec includes all mounting hardware and an Allen wrench, so you're ready to install straight out of the box.

M-LOK has become the standard on modern AR handguards, but it's not always the best interface for every accessory. This rail adapter solves that without compromise, letting you keep your handguard while expanding your mounting options. Whether you're building a dedicated night-rifle setup, a competition gun with multiple configurations, or just want future-proof flexibility, this is a no-fuss way to get there.
