The Vector MK1 Modular Rail is crafted as a bolt-on handguard extension tailored for the KRISS Vector CRB. Constructed from aluminum alloy it features a Cerakote ceramic firearms coating ensuring durability and a sleek finish. This rail mirrors the contours of the Vector's body strategically milled to provide a lightweight yet sturdy support structure. Along the three six and nine o'clock positions female threading allows for seamless attachment of the included KRISS Vector Picatinny Side Rail Kit which comes already installed. Designed specifically for a Gen 2 KRISS Vector this modular rail integrates directly with the weapon's body but is not compatible with Gen 1 models due to differences like the integrated flashlight mount.
