The GrovTec 3 Inch 7 Slot KeyMod Picatinny Rail (brand part no. GTSW228) is a compact accessory rail section that bolts onto any KeyMod handguard to add a true MIL-STD 1913 Picatinny mounting surface. GrovTec precision CNC machines the rail from solid, lightweight aluminum and finishes it in a Type III black hard anodized coating for a durable, low-glare look that resists wear from repeated accessory swaps. The seven-slot Picatinny pattern gives more mounting real estate than a shorter section, enough for a light, laser, sight, or other Picatinny-compatible accessory.
