TacFire MAR102 KeyMod Picatinny Rail 3" 7-Slot Black Aluminum

The TacFire MAR102 transforms KeyMod handguards into versatile mounting platforms with its precision-machined 3-inch Picatinny rail section. This lightweight aluminum rail adapter provides seven slots of standard 1913 rail space for optics, lights, grips, and other tactical accessories.

What Makes This Different

Unlike bulky permanent rail systems, the MAR102 offers modular flexibility through KeyMod's negative space mounting design. The rail weighs significantly less than traditional quad-rail systems while maintaining the same load-bearing capacity. Its anodized finish resists corrosion and wear better than standard mil-spec coatings, ensuring reliable performance across thousands of rounds.

Key Features

• Seven full Picatinny slots accommodate standard 1913 rail accessories
• 6061-T6 aluminum construction with Type III hard anodizing
• KeyMod negative space design reduces overall weapon weight
• Precision CNC machining ensures proper headspace and timing

Field testing demonstrates the MAR102's ability to maintain zero through rapid-fire strings and environmental changes. Competition shooters rely on its consistent return-to-zero when mounting and dismounting accessories. The rail's low profile reduces snag hazards during close-quarters movement while providing full functionality for duty and tactical applications.
