GrovTec GTSW367 3.8" 9-Slot M-LOK Picatinny Rail Section - Coyote Tan Cerakote

The GrovTec GTSW367 is a mid-length M-LOK to Picatinny rail section designed to add a short MIL-STD-1913 mounting platform to any M-LOK-compatible handguard. Constructed from a single piece of aluminum for a rigid, lightweight mounting surface, this section measures 3.8 inches long and provides 9 usable Picatinny slots for red dots, back-up iron sights, weapon lights, or laser aiming modules.

The GTSW367 is finished in Coyote Tan Cerakote, a durable ceramic coating that resists corrosion, abrasion, and handling wear, making it a natural match for FDE, coyote, and earth-toned rifle builds. The section attaches directly to M-LOK slots using the included mounting hardware and T-nuts for a low-profile, snag-free install on modern AR-15 and other M-LOK handguards.

Compact enough to clear muzzle devices and accessories, the GTSW367 is a clean solution for adding a small optics mount or a supplemental light or laser to a standard M-LOK handguard. As part of the GrovTec M-LOK Picatinny rail family, this 9-slot variant is the mid-length option in the Cerakote Tan lineup, sized for AR-15 and other modular rifle platforms.
