Gotical 3-Slot Rail DE Color Aluminium – 2-Piece Picatinny Rail Set for M-LOK (D-Earth)

Compact, Versatile Accessory Rail for M-LOK Systems

Designed with a D-Earth aluminium finish, the Gotical 3 Slot Rail provides a sturdy base for standard 21 mm picatinny accessories. This two-piece set keeps a slim profile while expanding your mounting options, essential for varying field tasks. Each rail measures 1.57 inches (40 mm) in length, offering a compact footprint that fits tight rail sections and compact handguards.

Built to last, the rails use 7075-T6 aluminium with stainless nuts, delivering high strength and corrosion resistance without unnecessary weight. The three-position slot design offers repeatable attachment points, enabling you to align sights, grips, or lights quickly and consistently. The system is fully compatible with M-LOK handguards, allowing you to integrate smoothly into modern platforms without sacrificing fit or stability.

What can you mount? These rails support a wide array of standard 21 mm picatinny accessories. Attach flashlights for low light tasks, bipods for steadier shots, forward grips for improved control, or sights for quick target acquisition. The two-piece design keeps installation flexible: swap in an accessory or reconfigure your setup with minimal effort, maintaining a lightweight, adaptable loadout.

Practical benefits and use cases

The two-piece format also makes storage and transport easier, enabling quick changes without reworking the entire setup.

Care and installation tips: tighten nuts to the recommended torque and verify alignment after mounting. Clean mating surfaces before installation and avoid over-tightening to protect threads. This Gotical rail is designed to integrate cleanly with M-LOK components, offering a reliable foundation for future upgrades without forcing a fixed configuration.
