This is the 12" Vltor Carbine Length Keymod Rail PolyLithic Upper Receiver. If you LOVE the Vltor MUR-1A You'll DOUBLE LOVE the VIS-KM series! Vltor has taken the Keymod rail and married it with the MUR Upper Receiver to create one solid Free Float system. This modular Upper Receiver is lightweight and is compatible with most Keymod accessories.
One of VLTOR's most innovative products is the Versatile Interface Structure (VIS) upper receiver assembly. VLTOR is
now introducing the VIS-KM, with the integrated KeyMod™ system. The KeyMod™ system breaks from the traditional
fixed quad rail setup and allows the operator to decide where accessories or rails are mounted. KeyMod™ also
allows for modularity between various manufacturer's accessories.
