kr 2 355,00

The KRISS Vector MK1 Modular Rail is designed as bolt on hand guard extension for your KRISS Vector CRB, and is made from aluminum alloy. The rail's shape follows the form factory of the KRISS Vector's body and is milled to reduce weight while still maintaining a rigid structure for support.

The KRISS Vector MK1 Modular Rail features female threading along the three o'clock, six o'clock, and nine o'clock surfaces for the attachment of a 7-slot Picatinny rail (additional Picatinny rails available separately). The MK1 Modular Rail mounts directly to the receiver of your KRISS Vector and will fit on GEN II models. The receiver's bottom Picatinny rail is accessible and accessories may fit as long as they do not extend past the Picatinny rail.

Recommended only for use with the 16" Vector CRB. Not intended for use with the 5.5" or 6.5" Vector SDP & Vector SBR as the barrel will terminate within the handguard.

Vector Mk1 Handguard includes:

  • One (1) 10-slot Picatinny rail mounted onto the top of the handguard
  • One (1) 7-slot Picatinny rail
  • Four (4) M4x0.7 screws for mounting the handguard to your Vector
