TacFire MAR101 KeyMod Picatinny Rail 2" 5-Slot Black Aluminum

The TacFire MAR101 KeyMod Picatinny Rail transforms KeyMod handguards into versatile mounting platforms for tactical accessories. This 2-inch rail section provides five Picatinny slots in a compact package that maintains the sleek profile of KeyMod systems. Built from aircraft-grade aluminum with a hard anodized finish, it delivers the mounting stability required for optics, lights, and grips without adding unnecessary bulk.

What Makes This Different

Unlike bulky quad-rail systems, the MAR101 allows selective accessory placement exactly where needed. The KeyMod mounting system creates a stronger connection than traditional screw-on rail sections, distributing stress across multiple contact points. At just 2 inches long, it provides essential mounting real estate while preserving the lightweight advantages that make KeyMod popular with competitive shooters and tactical professionals.

The hard anodized surface resists scratches and corrosion in harsh environments, from humid coastal conditions to desert sand.
