The Vector MK1 Modular Rail from KRISS USA is designed to be an add-on handguard extension for KRISS Vector CRB firearms. Made from durable aluminum alloy it features a Cerakote ceramic coating to enhance longevity and resistance. The shape of the rail is crafted to seamlessly integrate with the body of the KRISS Vector ensuring minimal weight and maximum structural support. This rail comes with female threading on the sides at three six and nine o'clock positions allowing for the attachment of the included KRISS Vector Picatinny Side Rail Kit which arrives pre-installed. Designed specifically for Gen 2 models the MK1 Modular Rail attaches directly to the Vector's body and is not compatible with Gen 1 models due to differences in flashlight mount integration. Key features include the inclusion of the Picatinny Side Rail Kit compatibility with Gen II models and female threading for versatile accessory attachment.
