GrovTec GTSW238 3.8" 9-Slot M-LOK Picatinny Rail Section - Black Hardcoat Anodized

The GrovTec GTSW238 is a compact 3.8" M-LOK Picatinny rail section that adds a standard MIL-STD 1913 Picatinny mounting surface to any M-LOK compatible handguard or forend. With nine usable slots, it provides just enough real estate to mount a red dot, backup iron sight, weapon light, laser, or other Picatinny-spec accessory.

Precision CNC machined from lightweight aluminum, this 9-slot rail is finished in a rugged Type III black hardcoat anodizing for long-term corrosion and wear resistance. The short 3.8" length keeps weight and bulk to a minimum, making it ideal as a secondary mounting point or anywhere you need a small Picatinny footprint on an M-LOK handguard.

The GTSW238 indexes directly to your M-LOK slots for a secure, repeatable mounting platform on AR-15s, pistol-caliber carbines, and other M-LOK-equipped firearms.
