Kriss TDI Vector MK1 Modular Rail Kit FDE — Gen II CRB

The KRISS Vector MK1 Modular Rail is a bolt-on handguard extension designed for KRISS Vector CRB Gen II models. Constructed from aluminum alloy and milled to reduce weight while maintaining rigidity, the MK1 follows the Vector’s form factor and provides additional mounting options. Female threading on the 3 o’clock, 6 o’clock, and 9 o’clock surfaces accepts the included Picatinny Side Rail Kit, which comes pre-installed. The MK1 mounts directly to the Vector body and is compatible with Gen II models; it will not fit Gen I Vectors due to the integrated flashlight mount on those models.
